This document describes an RFID and GSM based attendance system. The system uses RFID tags and a reader to track when students arrive and leave school/college and sends SMS alerts to parents. It consists of hardware components like a microcontroller, RFID reader, GSM modem and software like Keil Compiler. When a student's RFID tag is scanned, the time is logged to an EEPROM and an SMS is sent to notify parents. The system aims to save time and keep parents informed of their child's daily attendance through SMS messages in real-time.

3. INTRODUCTION
Purpose of the Project:
The basic function of the project is to alert parent through sms at which
the students report to college/school and leave from college.
What the project does to fulfill the purpose:
1. Conservation Of Time.
2. Day to day Performance of the child through Message.

Keil Compiler

6. component’s explanation
• Microcontroller: It is the Heart of the circuit. We will be using ATMEL’s AT89S52 microcontroller. The
controller that we will be using is ATMEL’s AT 89s52, which is a 40 pin microcontroller with 32 I/O lines. The
controller communicates with the RFID reader & the PC using RS232 protocol for which MAX 232 IC is
required.
• MAX232:
Microcontroller communicates with the PC using its inbuilt Serial Port. The voltage levels
are 0 & 5 Volts, but for the controller to
communicate with the PC we are using RS232 protocol so for
converting the CMOS (0-5) voltage levels into RS232 (±12) voltage levels we will be using MAX 232.
• Gsm modem: To send sms
• RTC:
Real Time Clock (RTC) is used to storing the real time. A battery is provided to the RTC so
that even when there is a power failure the time is intact. The controller communicates with the RTC using
the I2C protocol.
• EEPROM:
EEPROM is used to store the LOG’s of the person entering or exiting the premise.
The EEPROM will contain the person’s ID, time of scan & if the person is entering or exiting. The controller
communicates with the EEPROM using the I2C Protocol.
• LCD:
We will be using 2-Line, 16 characters LCD. This will be used to display the real time, scan
successful or not and other such details.
• Power Supply: The complete circuit works on 5v this voltage is generated in the power supply section
which basically consists of a step down transformer, a rectifier & a voltage regulator.
• RFID Module: To read RFID tags.

8. The Advantages of RFID vs barcode technology:
• No line of sight requirement.
• The tag can stand a harsh environment.
• Long read range.
• Portable database.
• Multiple tag read/write.
• Tracking people, items, and equipment in realtime.

9. Advantages
• Store data on a tag
• Can be hidden
• Work in harsh environment
Disadvantages
• Lack of standards
• Short range
• Cost

10. applications

• Colleges
• Industries

11. Future scope
• Livestock Tagging
• Wild Animal Tracking
• Electronic Article Surveillance (EAS)
• Automated Toll Collection
• Animal Husbandry
