- 1. 1 CHAPTER I INTRODUCTION Background ofthe Study This chapter includes the statemetn of the objectives, significance and scope of the study. Automated attendance monitoring and security access and control in every institution is indeed essential. With this, the institutions can keep track on their students and teachers’ absences and tardiness. This could also benefit the institution in saving money and paper works, time and effort while at the same time molding students producing more quality and discipline graduates as well as in monitoring and increasing teachers’ productivity and performance. Good attendance record could mean productive performance. However, tardiness and absenteeism preclude teachers especially students in having complete attendance resulting into low student grades and unfavorable post performances review. It is important to keep into note that attendance and its significance should be taught to students. Attendance is part of a students’ cumulative record. It is essential that good school attendance habits be established for later years when students seek employment. Traditionally, the monitoring of attendances is highly relied on the human’s effort and attention like the school dean assigned checker and the teachers. However, cases like the loss of checkers copy, human errors, erasures, inaccuracy, considerations and transparency could vary to the credibility of the record holder and that could also add up to the administrative stress.
- 2. 2 There are severalinstitutions all over the world had already adopted and used attendance monitoring system and classroom security automation to compellingly improve discipline and provide security. There are in fact several ways on doing attendance monitoring nowadays. This can be done either writing it in log books, using Bundy clocks or punch cards, also using computerized systems such as smart cards, biometrics, barcodes and Radio Frequency Identification (RFID) tags. According to Hamid, H. (2010), RFID has been used to access control in many different areas, from asset tracking to limiting access to restricted areas. Although the use of RFID systems in educational institutions is not new, it is intended to show how the use of it came to solve daily problems in other educational institutions. RFID is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders, thus the RFID is a wireless identification that normally comprises RFID Reader and RFID Tag. Hence, RFID is another suitable way or remedy that can be used in developing attendance monitoring system and security access and maintenance in solving institutional problems. Tiong Sing, G.C. (2012) described Automatic Access Control System using Student Identification Card Based on RFID Technology, the system has multiple functions and objectives. The first function is to provide security to help and support their university police to keep track of every entry activity in every student’s hostel rooms, offices, facilities and classrooms that prevents any theft activity and easily identify students or user who are registered on their system. The system contributed and replaced their conventional door locking mechanism with simple key interlock automated door security system controlled by RFID. The second function is it automatically record
- 3. 3 students’ attendance duringclass schedule while the teacher could maintain and print out the students’ attendance record. The system server was able to maintain and monitor both functions and brought a positive and drastic measure result in obtaining their objectives. In the Philippines, an institution had also adapted the use of RFID technology in attendance monitoring with Web- Portal and SMS. The system captures student RFID upon entrance allowing the parents to monitor their children’s presence inside the campus everyday. The system also provides a parent-portal web-based system tool to monitor the rank and grade of their child or children on a specific subject using a web-based system. Thus, the system could notify the parents if their child needs an immediate action or follow up together with the school teacher and the guidance counselor, Baltazar, Et. Al. (2012). The Attendance Monitoring System using RFID of the Notre Dame of Tacurong College is a centralized system that monitors and records employee’s daily time record. The system automates the recording of the time-in and time-out of every employee using RFID. This method helped save time, paper, effort and the DTR in-charge from hassle in generating and merging salary reports and the total of late and absences of all employees. In the College Department of Notre Dame of Tacurong College, an institution located at the Central Mindanao, is also having similar problems concerning attendance monitoring, But another particular problem of the school is their administrative overhead of every college classroom security. As an institution that has modern set-up, fully air- conditioned classrooms, problems unconsciously arise during every unsupervised student entry that are using its classrooms, and unit’s which leads into improper electricity consumption and wastage. This is because there was no present additional security
- 4. 4 measures installed thatcould prevent unsupervised entry or worst from a possible theft of any class room units. The classroom only has normal door knob and door lock keys which are left open during class hours that is why students can freely spend their free time inside open classrooms charging up their gadgets or refreshing themselves from the city’s unfavorable hot climate. The College of Arts and Sciences and Education (CAS-ED) assigned working students to check the attendance of every teachers evey period. This repetetive task of the working students is a hassle and tiresome for them to regularly perform the room-to-room routine. The dean entrusted the checker to keep the attendance record, and then later summarized to check the performance of every teachers in terms of attendance. However, the process is time consuming for the office to prepare. Sometimes it led to inconsistency. The teachers are using the conventional way of recording student attendance in paper or logbook manually while doing the traditional process of roll-calling names which is basically time consuming and is indeed troublesome for the teachers. This affects both teachers and students as time is spent on roll-calling, checking and verifying students’ names that is supposedly intended for lesson. The student attendance record of the teacher is kept. After every semester, the teacher summarizes and prepares a report that will be submitted to the dean. It is a slow and stressful process that could sometimes trigger human errors and could possibly result’s into inaccuracy and misplacement of record which leads to inconsistency. Along with this, the proponents conducted a study on Automated Classroom Magnetic Door Lock with Attendance Monitoring System using Radio Frequency Identification. The study could lower the stated problems based on this research
- 5. 5 hypothesis by implementingthe research in using a fail-safe type of electromagnetic door lock controlled by microcontroller and radio frequency identification technology. Objectives General Objective This study aimed’s to develop an Automated Classroom Magnetic Door Lock with Attendance Monitoring System using Radio Frequency Identification for Notre Dame of Tacurong College. Specific Objectives Specifically, the study aims to: 1. Design an algorithm to facilitate the attendance automation and classroom security entry access. 2. Design and implement a database structure for data storage which will hold all the data and information. 3. Design a miniature prototype model to simulate the attendance monitoring system and classroom magnetic door lock security feature.
- 6. 6 Significance of theStudy The result of this study on Automated Classroom Magnetic Door Lock with Attendance Monitoring System using Radio Frequency Identification is beneficial to the following stakeholders. To the Notre Dame of Tacurong College, The research could benefit the institution in maintenaining classrooms in providing security which will limit student entry as well as usage of every college classroom facilities which could impose observation in the consumption of energy during class days operation, hence, decreasing the school’s electricity bill. To the College Dean’s Office, the office may no longer require working students to manually deal the room-to-room attendance checking and consolidation of records just to create necessary reports needed by the school for evaluation. Hence, the system may help save time, loads of paper works, man power and energy. In using the attendance monitoring system, the dean could easily track and monitor the performance and the attendance records of every teacher using the Reports Form in the system. Through this Reports Form, the system allows the Dean to view and print records. To the School Physical Plant and Logistics Office, the electromagnetic door lock security feature may aid the janitorial personnel to improve the condition of classroom maintenance. This may also help school security personnel which are under the maintenance office in carrying out their duty from manually checking the college Smith Building’s classrooms that have valuable units.
- 7. 7 To the CollegeTeachers, They won’t need any log-books to do the manual attendance recording. They can easily keep track, monitor and record students’ tardiness and absences allowing them to monitor their students’ performances. The system can automatically count, summarize and print the attendance percentage of every student at the end of every semester providing them with ease during the production of reports instead of creating it manually. Furthermore, it could help the teachers to refrain from manual writing and calling student’s name individually that consumes valuable time during a class session. To the College Students, the students could easily tap their RFID’s during class schedules while the system automatically captures their RFID’s and count it as part of their tardiness and absences’ record. These data are directly counted inside the system that is stored inside the database. Through the system’s attendance monitoring and classroom security feature it may assist in molding and in embedding discipline especially to the students of Bachelor of Computer Science of the College Department to avoid rule deviation, tardiness, cutting of classes and other unethical misconduct patterns which students commonly do before or every after class sessions. Hence, it helps the students to adopt and practice punctuality, professionalism and adhere to proper school ethics and conduct. To the Parents and Student Guardians, they could be easily informed about their childrens' school performance through the reports taken from the system given by the school teacher or the school administrator. The report contains the student’s attendance records in which the school could use it as a basis for a student referral to the guidance office to undergo a counseling in preventing any further cause and effect detrimental to
- 8. 8 career and reputationof both student and parents or guardians inside and outside the campus. To the Bachelor of Science in Computer Science Program, this research may also contribute to the Bachelor of Science in Computer Science Program in providing them new ideas and insights in more advanced and effective algorithm formulation in the field of software development. To the Future Researchers, this may be considered as their basis for their future studies, explorations developments in the fields of security and attendance monitoring system and for new or other purpose and possibilities using the RFID technology. The results and findings of this study may give them some necessary information which they need for their study related to the proposed. Scope of the Study This chapter presents the scope and the capabilities of the proposed research system. The study focused mainly in the development of Automated Classroom Magnetic Door Lock with Attendance Monitoring System using Radio Frequency Identification Technology. The study was implemented in every College classroom of Smith Building of Notre Dame of Tacurong College, City of Tacurong. The system was made to record teachers’ and students’ attendances, classroom entry and exit logs, calculation of tardiness and absences.
- 9. 9 The system hadthe capability to retain current and previous records which could be used for future educational reference, entry log history or for security references. Only the system administrator was authorized to create and update subjects and schedules and assign teachers and students to it. Also, the system administrator had the authority to create system users, enroll student and teachers’ basic details that was then linked to their every RFID’s. The College Dean had limited access to the system. The dean can only view teachers’ and students’ attendance records and their statuses. The teachers were limited only to viewing students’ attendance records, students’ status. Both the Dean and Teachers can access the system using their assigned passwords. They were also allowed to print reports based on summary of the records of their main variables. Furthermore, in order to achieve the researcher’s objectives, the proponents will created two (2) miniature classroom doors which will served as the prototype model for the simulation of the system and its operation in order to showcase and attest its features and capabilities. The proponents could achieve the following goals by combining hardware and software. The system will used Microsoft Visual Studio 2015 Community Edition and its MSsql Local Database as its application software. Its hardware components included Gizduino v.5 for RFID Reader and RFID Card Communication, Arduino Uno to control Electromagnetic lock devices providing security and restriction on every classroom doors, 4x4 Keypad buttons for security override and 16x2 LCD for entry and attendance log status display. All hardware, aside from electromagnetic lock were placed into a 14 inches single wood board to hold every device. The wood board was covered by a glass frame according to its size securing all the wirings and devices.
- 10. 10 The proposed systemdid not have a backup battery to operate and assist the system operation during power interruptions.

RFID Reader refers to the device that detects and reads information from the RFID tag. System User refers to the teacher, dean and working student who use the proposed system for viewing and printing records.
- 12. 12 CHAPTER 2 REVIEW OFRELATED LITERATURES ANS STUDIES This chapter presents the relevant literature and studies related to the proposed system from different authors and books that may help in the development of the proposed study. According to Chow, H. et, al. (2012), RFID is a perfect solution which had a problem in security and monitoring the attendance. In recent years, there has been considerable interest in employing radio frequency identification (RFID) technology to support supply chain management for various industries and in institution, according to Chi-Kong Chan, The RFID technology system provides a cost-effective solution to some pragmatic requirements and technical challenges. A study in radio frequency identification based attendance system has also been developed in Bharti Vidhyapeeth College, Pune,India. The system is intended to automate the recording of student attendances by simply tapping the given student RFID to the reader during class entry. Also, their other objective is to eliminate human errors made by teachers during and to prevent students from their tardiness and absenteeism, et, al. Tapasvee, M. (2014). Another type of automatic attendance system using fingerprint verification technique was proposed by Chitresh, S. and Amit K. (2010). The fingerprint technique verification was achieved using extraction of abnormal point on the ridge of user’s fingerprint or minutiae technique. The verification confirms the authenticity of an
- 13. 13 authorized user byperforming one to one comparison of a captured fingerprint template against the stored templates in the database. The proposed automatic attendance system signals either true or false based on logical result of previous one to one verification of person’s authenticity. Moreover, RFID based Attendance Management System has been developed by Shashank Shukla, Shailee Shah, Pooja Save from the Department of Information Technology, Thakur College of Engineering & Technology in Mumbai University, India. Their attendance monitoring system can automatically capture student's attendance by flashing their student card at the RFID reader, thus solving the problems in unnecessary consumption of class time by the students to find and sign their name on the attendance sheet, mistakenly or purposely sign another student's name and misplacement of attendance sheet.This is the main motive of their system and in addition having an online system accessible anywhere and anytime can greatly help the lecturers to keep track of their students' attendance. Looking at a bigger picture, deploying the system throughout the academic faculty will benefit the academic management as students' attendance to classes was is one of the key factors in improving the quality of teaching and monitoring their students' performance. Besides, this system provided valuable online facilities for easy record maintenance offered not only to lecturers but also to related academic management staffs especially for the purpose of students' progress monitoring. Furthermore, another study relating to security access has been made by Nor Amiyana Binti, M.A. (2011) from Universiti Teknikal Malaysia Melaka which is entitled Attendance and Access Control System Using RFID System designed specially for Companies that lack in controlling employees and outsiders entry flow. People
- 14. 14 (employees or outsiders)can go in and out of the company’s premises with minimal supervision. Manual log booking and attendance system for employees and visitors has the absolute potential of wasting valuable time since the outsiders apecially employees needs to line up and wait their turn to tally up hand-written punch clock cards manually while entering the company gate. The proposed system resolves the stated problems by the use of RFID. Important records such as picture and time of entry or exit are added and managed. The attendance system monitors and implements an access control based on the presence of employees and visitors. The system also recorded and calculated working hours of employees in order to pay their wages and evaluate the jobs accurately.
- 15. 15 CHAPTER 3 TECHNICAL BACKGROND Inthis chapter discuss the technicality of the research study by which it describes the type of the project to be developed, parts and its functionality. The primary purpose of an RFID system in this application area is to detect the presence and absence of the teacher and student data to be transmitted through wiring connection, called tag, which is read by an RFID reader and processed according to the programmed instructions on the personal computer (PC). The proposed system provides solution to lecture attendance problem through coordinated hardware and software design handshaking data communications between RFID tag and RFID reader serially interfaced to the digital computer system. Figure 1. Network and System Architecture.
- 16. 16 Figure 1 representsthe network and system architecture which comprises the hardware and software connection of the system as a whole. In order for the system to be fully functional, the first operation starts in registering student and teachers’ details which is handled by the system administrator. The system administrator gathers the teachers and students details and the serial code of their given RFID’s which will be registered in the Teachers and Students Form for their accounts. Assuming that the subject and schedules are already created, the admin will assign teachers and students to the schedules to the system using MsSql Local Database system and Visual Studio 2015 application software inside the centralized computer server. In order for anyone to have an access to every classroom, the teachers will use their assigned RFID’s containing their information tapping it to RFID reader. RFID reader will convert the analog signal into digital and pass the converted data to the GizDuino v.5 microcontroller sending it to the computer server. The system application inside the centralized computer server will verify the received data and compares it to the stored data inside the data base management system for user validation or filtration. Successful log-in and log-out will be counted and stored in the database for the attendance recording. Whether the result of a transaction either successful or not, the programming application software with the help of the centralized computer server will send back a signal to the GizDuino and decide whether to command or not the electromagnetic lock to change its status and projecting message to the 16x2 LCD successful or not. School security or maintenance personnel classroom entry will be possible using the 4x4 universal keypad. The passcode that is being typed by any personnel will be processed and compared inside the Arduino Uno microcontroller and its
- 17. 17 pre-defined logic. Rightcombination of entered pic code in the Arduino Uno will will trigger the Gizduino microcontroller to operate the relay switch that controls and cut the power supply of the electromagnetic lock. Teachers and students attendance records summary can be produced using the printer which is connected to the computer server. In order to use the attendance monitoring system, Hardware and software components of the system are required to be fully functional: Figure 2. Passive RFID Tag (125 KHzMango). Radio-frequency identification (RFID) contains and electronic tag or transponder microcontroller which can hold RFID serial data, RFID uses radio waves signal to transfer data. Tags can be read at once as long as they are passed within close enough proximity to an RFID reader. RFID contains serial codes and which is then processed and compared in the system using a host computer to identify the user’s information. There are many variety of RFID that is being used in the industry but the most common types of RFID are Passive and Active RFID. Passive RFID do not use any battery to operate instead it leeches power from the RFID reader to become active and detectable. The
- 18. 18 passive RFID operatesin a low frequency, it works on 125 kHz and it has approximately from within 4 inches up to a half meter reading range and mostly used for short reading range applications. Kamran Ahsan, (2010). In this research, Passive RFID is used in the operation of attendance monitoring and in classroom security access with and through RFID Reader device. Figure 3. GizDuino 5.0 RFID Reader. RFID reader works as a central place for the RFID system. It reads tags data through the RFID antennas at a certain frequency. Basically, the reader is an electronic apparatus which produce and accept a radio signalsm. The antennas contains an attached reader, the reader translates the tags’ radio signals through antenna which acts as a Transceiver depending on the tags capacity. The reader consist a build-in anti-collision schemes and a single reader can operate on multiple frequencies. As a result, these readers are expected to collect or write data onto tag and pass it to computer systems using USB cables to serial ports through a Gizduino or Arduino microcontroller.
- 19. 19 Figure 4. GizDuinoVersion 5 w/ATmega328P. In order for the centralized computer system to capture RFID card, the system will use Gizduino to control the classroom entry and access. This device sends a signal to the electromagnetic lock to control and change the magnetic lock’s status. Gizduino is another version product of E-Gizmo Company similar to Arduino or Arduino Uno. It is an open-source and programmable microcontroller development board. You can use the Gizduino to read sensors and control things like motors and lights. This allows you to upload programs to this board which can then interact with things in the real world. With this, you can make devices which respond and react to the world at large. Basically, if there is something that is in any way controlled by electricity, the Gizduino can interface with it in some manner and even if it is not controlled by electricity, you can probably still use things which are (like motors and electromagnets), to interface with it.
- 20. 20 Figure 5. 4x4Universal Keypad Universal keypad buttons is an input device that has a set of buttons arranged in a block or "pad", these buttons are labelled with digits (numerals), symbols and alphabetical letters. Keypad is used in the system for manual override of classroom security for the security and maintenance personnel use. The entered pin code will be processed to the Arduino Uno R3 microcontroller. Figure 6. Arduino Uno Microcontroller R3.
- 21. 21 Arduino Uno isan open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. Arduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators. The microcontroller on the board is programmed using the Arduino programming language (based on Wiring). In the system, this is used to receive data from the 4x4 universal keypad which processes and compares it to the pre-defined programmed logic codes and transmits a signal from its digital PIN 0 to Gizduino microcontroller Pin 11. Result of the activity will be projected to the 16x2 Liquid Crystal Display. Figure 7. 16x2 Liquid Crystal Display 1602A. Liquid it is a controller circuit integrated device display terminal that could be connected to GizDuino. It could display digital output message response relay in order to provide an interaction between the system and the user. LCD responds and displays the characters or codes entered by school personnel that enable them to interact with the computer server when accessing a. The LCD displays a message of teacher’s entry status as well as a message in recording student’s attendance process if it’s granted or not.
- 22. 22 Figure 8. CentralizedComputer Server (PC). In order for the system to become operational, a centralized computer server (CCS) is needed. The computer server will serve as the front-end of the system that provides an interface between the RFID hardware and application based system, which is the “main brain” of the system. It is used to network multiple RFID interrogators and GizDuino and Arduino Uno microcontrolles to centrally process input and output information using USB wires and Serial Ports. The data that flows to computer enters through computer serial ports. Serial ports are detected in the computer as ComPort or Communication Ports. Personal Computer (PC) consist a running attendance monitoring application software using Visual Studio 2015. Figure 9. Visual Studio.net 2015.
- 23. 23 VS.net (Visual Studio.NET)is an object-oriented programming language from Microsoft. It is the .NET version of the Visual Basic (VB) programming language. Like all .NET languages, VB.NET uses the Common Language Runtime (CLR) for program execution. Visual Studio is used to program the attendance monitoring system that allows the admin and user to create, read, update and delete teacher, student, subjects and schedule details as well as in creating user and setting the user limitation and system access to the application. Furthermore, it is also used for DTR function feature. Visual Studio only allows and limits registered teachers, working students and dean as a user only in previewing and printing records and reports. The information that are created and projected or viewed in the attendance monitoring system are stored and retrieved inside its Local Database called MsSql Local Database 2015 which is part of the package of Visual Studio application installer. Figure 10. MsSql Local Database 2015. Database Technology is used for large scale of data. In this study, the researchers will be dealing with data. A database is needed to store and organize information in an easy and convenient way.
- 24. 24 Database is apart of the centralized computer server or personal computer (PC) that handles the storage, retrieval, and updating of data in a computer system. The Database system contains an SQL server in which all the data will be stored. All the information loaded to the GUI will come from the system’s Database server. This will basically hold the entire user’s (Students and Teachers) data, class schedules, time and other necessary information needed for attendance automation and in accessing classroom magnetic locks. Pronounced either "Microsoft S-Q-L" or "MS Sequel," It is an open source relational database management system. It is based on the structure query language (SQL), which is used for adding, removing, and modifying information in the database. Successful or failure classroom attendance and door access will vary or depend based on the registered data inside specially for controlling door access in changing electromagnetic lock state or statues. Figure 11. Ebelco 300/600 – LED Electro Magnetic Lock (Fail-Safe). To establish and maintain classroom security and restriction, a device called Electro Magnetic Door lock will be the suitable component for the problem. The Magnetic Door lock device is a simple locking device that consists of a magnetic lock and armature plate with no moving parts and it purely works due to the magnetic field.
- 25. 25 Therefore the magneticlock is truly fail-safe (Power to lock). Magnetic lock or mag lock uses an electrical current to produce a magnetic force. When a current is passed through the coil, the magnet lock becomes magnetized. The door will be securely bonded when the electromagnet is energized holding against the armature plate. Access control systems are operated by peripheral device (ie.Numeric Keypads, RFID Tag and RFID Reader) to identify the user whether access is permitted or not. Controlling multiple electromagnetic lock in this study, it requires a printed circuit board in which transistors, resistors, Gizduino and Arduino Uno microcontroller are all being connected to a customized Printed Circuit Board. Using PCB, the computer server manipulate or control the flow of electric current which supplies the electromagnetic lock’s power through microcontrollers. Figure 12. Customized Printed Circuit Board (PCB). PCB is an electronic circuit consisting of thin strips of a conducting material such as copper, which have been etched from a layer fixed to a flat insulating sheet called a printed circuit board, and to which integrated circuits and other components are attached. the board base for physically supporting and wiring the surface-mounted and socketed
- 26. 26 components in mostelectronics. This customized printed circuit board holds the microcontroller pins and other electronic devices such as 12 Volts replay, Transistor 2n2222, Resistor 4.7kohm and the Cannon M-838S power supply. Figure 13. Self-Lock Channel 12 volts Relay. Relay is an electromagnetic device which is used to isolate two circuits electrically and connect them magnetically. They are very useful devices and allow one circuit to switch another one while they are completely separate. They are often used to interface an electronic circuit (working at a low voltage) to an electrical circuit which works at very high voltage. For example, a relay can make a 5V DC battery circuit to switch a 230V AC mains circuit. Thus a small sensor circuit can drive, say, a fan or an electric bulb. A relay switch can be divided into two parts: input and output. The input section has a coil which generates magnetic field when a small voltage from an electronic circuit is applied to it. This voltage is called the operating voltage. Commonly used relays are available in different configuration of operating voltages like 6V, 9V, 12V, 24V etc. The output section consists of contactors which connect or disconnect mechanically. In a
- 27. 27 basic relay thereare three contactors: normally open (NO), normally closed (NC) and common (COM). At no input state, the COM is connected to NC. When the operating voltage is applied the relay coil gets energized and the COM changes contact to NO. In this study, relay is trigger by the Gizduino and Arduino Uno microcontroller. Both microcontroller runs on 5-9 Volts, thus, the power of both microcontrollers are not enough to trigger the 12 Volts electromagnetic lock. With the help of the transistor and a resistor, power can be controlled and increase which is enough voltage for the relay. Through transistor and a resistor, the 5-9 volts power from the microcontrollers will be converted. Thus, allowing it to either change the connection status of the 12 volts relay in controlling the flow of the current supply powering the electromagnetic lock. To further define, The 2N2222 transistor is a common NPN bipolar junction transistor (BJT) used for general purpose low-power amplifying or switching applications. It is designed for low to medium current, low power, medium voltage, and can operate at moderately high speeds. It was originally made in the TO-18 metal can as shown in the picture. A 4.7kΩ resistor has yellow, purple, and red stripes in that order. The last stripe represents the tolerance. Gold means ±5%. Figure 14. Potentiometer 10kOhm.
- 28. 28 Figure 14 isthe measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential (voltage); the component is an implementation of the same principle, hence its name. Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment. This is used as a peripheral device or the Liquid Crystal Display (LCD), it controls the intensity by adjusting the potentiometer which affects the voltage flow or supply. Figure 15.

It includes the Operational Diagram, Context and Physical Data Flow Diagram, Entity Relationship Diagram, the Developmental Approach, Schedule and Timeline of activities, and the Budgetary Outlay and Cost Management. Operational Diagram: Figure 17. Operational Diagram of Automated Classroom Magnetic Door Lock with Attendance Monitoring System using Radio Frequency Identification. Figure 17 shows how the Automated Classroom Magnetic Door Lock with Attendance Monitoring System using Radio Frequency Identification works. The system operation starts during the Users Tapping of their RFID’s assuming that the teachers’ and
- 31. 31 students’ information ofthe current school year has been registered in the Centralized Computer Server in its Database by the system administrator. In order to access and use a classroom, the Teacher must be the first user to tap-in using his or her assigned RFID to the RFID Reader device. The system will compare, validate and record the teacher’s RFID and log-in information to the Database Management System. The result of the teacher’s access transaction will then trigger the Centralized Computer Server to send a signal to operate the Gizduino microcontroller activating the Electromagnetic Door Lock’s status to its de-magnetized mode. Changing the electromagnetic lock status, the system then activates the attendance recording feature for the teachers and students in a particular class schedule. The students can now tap their RFID’s to the RFID reader for recording students’ log-in. both teacher and student entry access and attendance recording are prompted by the 16x2 Liquid Crystal Display whether for or failed successful transaction. When leaving the classroom after the class session, the students are obliged to re-tap their RFID’s for their log-out information. To close a classroom and to magnetize the magnetic lock, the teachers must also re-tap their RFID’s. This action will record teachers and students log-in and log-out while the system calculates and summarizes both users’ attendance records to the system’s database and count as one record entry for the day. Instances such as emergency or classroom maintenance and security, school personnel without having or any issued RFID with them can access the classrooms using the universal keypad by typing the personnel or classroom access code. When De- magnetizing the lock status, the system allocates five (5) seconds to return to its magnetized status. The teacher and students can open the door from the inside using the
- 32. 32 push button exitdevice. Monitoring System Using Radio Frequency Identification is divided into three (3) sub parts that explains more about the system. Figure 18. Accessing Classroom and Attendance Monitoring using Radio Frequency Identification. Figure 18 shows that using the teacher RFID tag serves as the key to trigger the system to de-magnetize the electromagnetic lock which opens the classroom door and activates the system’s attendance monitoring. To start the process, the teacher will first tap his/her RFID card to the RFID reader. Using his or her RFID card, this allows the teacher to communicate with the centralized computer server and its system application through RFID reader and Gizduino microcontroller. The RFID reader will capture the analog signal from the teacher’s RFID and sends the information to the Gizduino microcontroller converting it into digital data in a way for a computer could understand. Relaying this digital data to the centralized computer server allows the system to analyze and compare if the detected RFID card information is from a teacher or not, this is made possible using the records
- 33. 33 inside its LocalDatabase system. This process allows the system logic to decide and trigger whether to suspend the power supply de-magnetizing the electromagnetic lock. After the teacher logs-in, the student can now tap their RFID card for their individual log-in attendances. After the class session has ended, all students must be the first to tap out before their teacher in order for the system to record it as a student log-out. This process is followed by the teacher tapping out his or her RFID card telling the system that the class session has already ended. This will stop the attendance monitoring and recording system on a particular subject schedule and signals the system to trigger the gizduino microcontroller to magnetize the electromagnetic lock closing the door. Finally, the system will count and summarize the attendance records of both teachers and students whether it’s a tardy late or an absent. Instances like students tapping their RFID card first will only limit them from opening the classroom door. Also, for the students who failed to log-out before their teacher will be counted as absent. Students and teachers who failed to log-in before the allocated time of a class schedule will be counted as late. Figure 19. Using Push Button inside the Classroom.
- 34. 34 In this figure,the push button will be used inside the classroom. Either students or the teacher can use the push button for their personal necessities, emergencies and/or evacuation. The push button is connected to the Printed Circuit Board (PCB) through PIN 4 triggering the 12 volts (V) Relay Direct Current (DC) cutting the power supply to unlock the Electromagnetic Lock State. Figure 20. Overriding the System Using 4x4 Universal Keypad. In the figure shown above, the security or maintenance personnel can access every classroom using the given passcode to override the classroom door lock security system for classroom maintenance purposes. Using keypad, the security personnel can also access the classroom for monitoring, security or emergency situation purposes. The Electromagnetic lock status is lock and powered by default as well as the 16x2 LCD message displaying “Welcome, Pin Code:”. If the personnel would like to access any classroom, the personnel will type his or her passcode using the universal keypad located outside the classroom. Upon typing his or her four (4) digit passcode
- 35. 35 enter by pressing“hashtag” (#), the Arduino Uno microcontroller will then compare the entered passcode to the data programmed inside Arduino Uno. If the passcode is correct, the Arduino Uno microcontroller will display “Pin Code Correct!, Door is Open.” and at the same time it will throw a data through its PIN 0 to the PIN 12 of Gizduino microcontroller disabling the power supply of the Electromagnetic Lock through PIN 13. After disabling the magnetic locks power supply, there will be 5 seconds delay in order for the Arduino Uno microcontroller to reactivate the 12 volts (V) Relay resupplying the 12 volts(V) power supply to re-magnetizing the electromagnetic lock. Else, if the given password by the personnel is incorrect, the Arduino Uno microcontroller will send a digital data to the 16x2 LCD displaying a message “Wrong Pin Code, Please try again” and the Electromagnetic Lock won’t be unlocked.

- 47. 47 CHAPTER 5 RESULTS ANDDISCUSSION Figure 24. Automated Classroom Magnetic Door Lock with Attendance Monitoring System using Radio Frequency Identification frequency. Figure 24 is the whole structure and conceptual model of the entire system. Administrator, Student, Teacher, and Personnel are the main users of the system. Thus, the Admin will facilitate or control the system inside the desktop computer, the student and teacher will tap their RFID tag in order for them to register their personal information and login or logout between classes. The RFID Reader that connects to Gizduino will serve as bridge between RFID tags and desktop computer. The data that comes from RFID tags and student and teacher personal information will be saved into database that was pre-installed in the desktop computer using the visual studio. The personnel will enter his/her four (4) digit passcode in universal keypad, the Arduino Uno will evaluate the passcode entered to its own secret passcode. If the passcode is correct, the Arduino Uno will send a data to the LCD that will display a message, the Arduino Uno will send a
- 48. 48 signal to Gizduinothat controls the Printed Circuit Board (PCB) to trigger the electromagnetic lock to open. Else if the passcode entered in Arduino Uno is wrong, the Arduino Uno will not send a signal Gizduino, the electromagnetic locked will remain lock until the correct passcode will be entered. Specific Objective 1. Design an algorithm to facilitate the attendance automation and classroom security entry access. Figure 25. Algorithm flowchart for teacher attendance monitoring and classroom security access and entry.
- 49. 49 Figure 25. showsthe process flow for teachers in using the system. The User (teacher) would tap his or her RFID card to the RFID Reader then the data will pass through Gizduino to the Computer. This is the first security level of the system in controlling the door lock status. After the data has entered the system, the application will compare and check the RFID tag data to the MsSql 2015 Local Database and verifies if the user’s RFID card is a teacher’s RFID or not, otherwise, the system will deny access and prompts the user as unregistered displaying the second message as door status as locked maintaining it as closed. If the tapped RFID of the user is identified as teacher’s RFID, the system will activate its second level of security function. The system will checked if the detected teacher’s RFID has a class schedule on a specific time. If there was, the system will automatically record it as attendance and treats it as teachers log-in inside the Local Database Server displaying a message while at the same time changing de-magnetizing electromagnetic lock opening the door allowing the teacher and student to enter the classroom. During this state, the system’s attendance monitoring for student is activated allowing students to tap their RFID’s for their log-in. Before or during the end of the class session, the students are required to tap again their RFID’s for student attendance log-out. The second time the teacher taps his or her RFID, this activates the electromagnetic lock into magnetize state securing the door and displaying a message. This also treats the teacher’s second tap as log-out and records it to the database.
- 50. 50 Figure 26. Algorithmflowchart for student attendance monitoring. Figure 26 shows the process flow for student attendance monitoring and recording. After the teacher tapped in and activated the attendance recording system for the students, the students would tap their individual RFID’s to the RFID reader in order for the system to compare it to the local database. If the students’ RFID tag data matches the record inside the local database, it will then verify if the student is enrolled on the class schedule in order to treat it as log-in in the system and displays Log-in success
- 51. 51 message, otherwise itprompts the student an access denied message which is a failure in recording attendance log-in. In order for the system to consider a counted student attendance, the system must consider a pair or a complete set of student log-in and log-out logical condition. This logical condition programmed inside the system will determine if a student will be counted as absent or not. Students who failed in tapping their RFID for log-out will be considered by the system as absent. This is to prevent student cutting classes. Figure 27. Algorithm flowchart for security and maintenance personnel classroom access. Figure 27 shows the process flow in accessing classroom security by overriding it using set of programmed codes. Security and maintenance personnel of the school will
- 52. 52 type the accesscodes which is a combination of four numbers and pressing “#” special character. By pressing “#” special character, the entered pin code will be processed and validated by the microcontroller. Correct pin code sets the electromagnetic status to de- magnetized mode and releases its lock while displaying a “Welcome, Door is Open” message projected to the 16x2 liquid crystal display (LCD) allowing any school personnel to enter the room. Otherwise, the door will remain closed and the electromagnetic lock stays on its magnetized state maintaining its lock mode. Specific Objective 2. Design and implement a database structure for data storage which will hold all the data and information. Figure 28. Database Structure of Automated Classroom Magnetic Door Lock with Attendance Monitoring System using Radio Frequency Identification.
- 53. 53 Figure 28 illustratesthat the system administrator is the only person who is authorized to register student and teacher RFID and basic information details to the system in MsSql 2015 Local Database inside Visual Studio 2015. To do this, the administrator will log-in as a user that has full access on the Main Form of the system using the Authentication Form. The admin will use the Teacher and Student Registration Forms to add their individual information to the system. The administrator will also register their every RFID’s using a separate RFID Reader. These students and teachers RFID’s are linked to their individual registered accounts in order for the teachers and students to use and connect the attendance monitoring system. Specific Objective 3. Design a miniature prototype model to simulate the attendance monitoring system and classroom magnetic door lock security feature. Figure 29. Miniature prototype simulation model.
- 54. 54 Fig. 29. showshow the actual simulation of accessing the door using the RFID and recording of attendance, Push Button and Universal Keypad. The teacher’s RFID will be used to manipulate the electromagnetic state to open and close the classroom door and also for teachers’ attendance time in and out. Students will use their RFID cards to register their attendances. Students’ attendance monitoring activity is made during or in between class hours. By doing this, the system will use RFID reader to capture RFID tag information. RFID attendance monitoring process is handled by the Gizduino microcontroller and forwarded to the computer server. Recording attendances and opening classroom is handled by the Visual Studio 2015. Data comparison and record storing are processed using MsSql Local Database. Security and maintenance personnel can access the classroom without using RFID. It is done using keypad, 16x2 LCD and Arduino Uno. Personnel will only type a set of pin codes using the keypad. After the entering of pin code, the 16x2 LCD will display a message for either successful or unsuccessful activity. To control the magnetic lock state using keypad, the command will vary on the logic programmed inside the Arduino Uno microcontroller.
- 55. 55 CHAPTER 6 CONCLUSIONS ANDRECOMMENDATIONS Conclusion After developing the research project, the results showed the Automated Classroom Magnetic Door Lock with Attendance Monitoring System Using Radio Frequency Identification system satisfied the entire objectives. When it was tested, it showed that through the attendance monitoring, the accuracy, reliability, convenience and security satisfied the needs of the teachers and students. It only proved that proposed study was a manageable system that is capable of recording attendance accurately and securely in lesser time. It was consistent in terms of providing correct information and updating of student’s and teacher’s attendance; it can be easily accessed by the school dean. The system was specifically developed for attendance monitoring, security access and maintenance which used a technology that is being used nowadays. The research implied that the system was designed as user-friendly and easy to access. Therefore, the researchers say that Automated Classroom Magnetic Door Lock with Attendance Monitoring System using RFID system is ideal for attendance monitoring.
- 56. 56 Recommendations After thorough study,the researchers strongly recommended the following: 1. The system should have a centralized monitoring system control capable to network all Automated Classroom Magnetic Door Lock with Attendance Monitoring System. 2. The system should not be limited to Microsoft Operating System (O.S.) and Visual Studio.net platforms but should also in other platforms (i.e. Linux, Mac O.S., iOS, Java programming software). 3. The system should also provide access to students in viewing their attendance in the web browser or in a mobile application using the Internet. 4. The system should use two database platforms to back up all files. 5. The system should have a power backup device called Uninterruptible Power Supply or (UPS) in case of power failure.
