3. Introduction:
Security is a major concern in our day to day life, and digital door locks have
become an important part of these security systems. There are many types
technologies available to secureourplace, like PIR Based security systems, RFID
based Security system, Laser security alarms, bio-matrix systems etc. Even now,
there are Digital locks which can be operated using our smart phones, means no
more need to keep different keys, just one smart phone can operate all the locks,
this concept is based on Internet of Things. In this project, we have explained a
simple using the microcontroller AT89S52, which can only be unlocked by a
predefined code, if we enter the wrong code, thesystem alerts by siren the buzzer.
This system mainly contains AT89S52 microcontroller, keypad module, buzzer
and LCD. At89s52 microcontroller controls the complete processeslike taking
password form keypad module, comparing passwords predefined password,
driving buzzer and send status to LCD display. Keypad is used for inserting
password into the microcontroller. Buzzer is used for indication of wrong
password and LCD is used for displaying status or messages on it. Buzzer has
inbuilt driver by using a NPN transistor.
Automatic RoomLight controlling System is a microcontroller based project that
automatically turn on oroff the lights in a room. Electricity, being one ofthe most
important resources, must be utilized carefully. The project implemented here is
one such project where the microcontroller based system automatically controls
the room lights.
4. Existing System:
Manual doorlock system
For opening the dooruse the key system.
Low security system.
We often forget to switch off lights or fans when we leave a room. By
using this system, we can intentionally forget about the lights as the
system will automatically take care of them.
Aim of the Project:
• Electronic codelock using AT89S52 Microcontroller, which can only be
unlocked by a predefined code, if we enter the wrong code, the system
alerts by siren the buzzer.
• The project can also make high security.
• The aim of this project is to automatically turn on or off the lights in a
room by detecting the human movement. We implemented this project
using 8051 Microcontroller and two Infrared (IR) sensors
Block Diagram:
5. Working Explanation:
This system mainly contains AT89S52 microcontroller, keypad module, buzzer
and LCD. At89s52 microcontroller controls the complete processes like taking
password form keypad module, comparing passwords predefined password,
driving buzzer and send status to LCD display. Keypad is used for inserting
password into the microcontroller. Buzzer is used for indication of wrong
password and LCD is used for displaying status or messages on it. Buzzer has
inbuilt driver by using a NPN transistor.
Components Required:
• 8051 Microcontroller (AT89S52)
• 4X4 Keypad Module
• Buzzer
• 16x2 LCD
• Resistor (1k,10k)
• Network resistor (10K)
• Capacitor(10uf)
• Red led
• Bread board
• IC 7805
• 11.0592 MHz Crystal
• Power Supply
• Connecting wires
6. Component Description:
4X4 Keypad Matrix:
• In this circuit we have used multiplexing technique to interface keypad to
the 8051 microcontroller, for entering the password in the system. Here we
are using a 4x4 keypad which has 16 keys
• If we want to use 16 keys then we need 16 pin for connection to 89s52,
but in multiplexing technique we need to use only 8 pins for interfacing 16
keys
• Multiplexing technique is a very efficient way to reduce number of pins
used with the microcontroller for providing the input or password.
Basically this technique is used in two ways - one is row scanning and
other one is column scanning
7. LCD Display Module:
LCD (liquid crystal display) LCD (liquid crystal display) is the technology used
for displays in notebook and other smaller computers. Like light-emitting diode
(LED) and gas-plasma technologies, LCDs allow displays to be much thinner
than cathode ray tube (CRT) technology.
AT89S52 Microcontroller:
The AT89S52is a low-power, high-performance CMOS 8-
bit microcontroller with 8K bytes of in-system programmable Flash memory.
The device is manufactured using Atmel's high-density nonvolatile memory
technology and is compatible with the indus- try-standard 80C51 instruction set
and pinout.
8. IR Sensor Module:
• An Infrared or IR Sensor is a simple circuit that is used to detect objects
(Proximity Sensor) or measure distance (Range Finder). An IR Sensor
consists of 3 components: an IR Transmitter (IR LED), an IR Receiver
(like a Photo Diode) and a signal processing circuit.
• We have used reflective type IR sensor modules in this project. The
detailed circuit diagram of the module is shown in the following image.
5V Relay Module:
A 5V Relay Module is used in this project which helps 8051 Microcontroller to
operate high voltage AC loads like a light. The detailed circuit of the Relay
Module is shown in the following image. It consists of a 5V Electromechanical
Relay, an Optocoupler IC, transistor, two resistors and two diodes.
9. Proteus Circuit Design of Our Project:
Circuit diagram for this Digital lock using 8051 has been shown below and can
easily be understood. Keypad module’s Column pins are directly connected to
pin P0.0, P0.1, P0.2, P0.3 and Row pins are connected to P0.4, P0.5, P0.6, P0.7
of 89s52 microcontroller’s port 0. A 16x2 LCD is connected with 89s52
microcontroller in 4-bit mode. Controlpin RS, RW and En are directly connected
to pin P1.0, GND and P1.2. And data pin D4-D7 is connected to pins P1.4, P1.5,
P1.6 and P1.7 of 89s52. And one buzzer is connected at pin P2.6 through a
resistor.
10. • we have used modules for Relay and IR Sensorand hence, the connections
are shown with respect to those modules only. Corresponding circuit
diagrams are also provided.
• For the circuit design, a 16 x 2 LCD Display, two IR Sensors and a 5V
Relay Module must be connected to the 8051 Microcontroller. First,
connect the 8 data pins of the LCD to PORT1 pins i.e. P1.0 to P1.7.
• The 3 control pins of LCD i.e. RS, RW and E are connected to P3.6, GND
and P3.7pins respectively. A 10 KΩ Potentiometer is connected to contrast
adjust pin of LCD i.e. its pin 3.
Hardware Circuit of Project:
Wehave used a predefined password inthe program, this password canbedefined
by the user in the code below.
When user enters a password to the system, then system compares the user
entered password with stored or
predefined password in Codeof Program. If a match occurs then LCD will show
“Access Grated” and if the
11. password doesn’t match then LCD will show “Access Denied” and buzzer will
continuously beep for some time. Here we have
used string.h library. By using this library we can compare or match two strings,
by using “strncmp” function.
• In this project, an automatic room lighting system is developed using 8051
microcontroller. The working of the project is explained here.
• The main component of the project is IR Sensor and we have used two of
them. The placement of the sensors is important as it will determine the
functioning of the project.
• Practically speaking, both the sensors must be placed on the either side of
the door or entrance of the room. The sensor placed on the outside of the
room is named as Sensor1 and the sensor, which is placed on the inside is
named Sensor 2.
• When a persontries to enter the room, Sensor1 detects the personfirst and
then Sensor 2. This action will indicate the 8051 Microcontroller that the
person is entering the room.
12. Applications:
• Digital Password door Controlling system with password , it can be used
to turn on the doorin a room when a personenters the room and turn it off
when the person leaves the room.
• The project can also secure for any low security
• The project can be modified with LEDs and as the access password in the
room doorand also we enter the wrong code, the system alerts by siren the
buzzer.
• Automatic RoomLight Controlling with Bidirectional Visitor Counter can
be used to automatically turn on the light in a room when a person enters
the room and turn it off when the person leaves the room.
• The project can also be dubbed as a Bidirectional Visitor Counter it is an
integral part of the Automatic Room Lighting circuit.
• The project can be modified with LEDs and as the number of persons in
the room increases, the number of LEDs turning ON also increases.
Future Plan:
In future using the idea make digital password door controlling system with
voice password , it can be used to turn on the doorin a roomwhen a person
enters the room and turn it off when the person leaves the room.
The project can also make high security.
