Password Based Door Lock System Using 8051 Microcontroller Ppt

In this project i am going to design a simple automatic door lock system using 8051 89c51 89c52 microcontroller 16 2 lcd 4 4 numeric keypad and a digital lock.

Password based door lock system using 8051 microcontroller ppt.

Door access system digital code lock keyless entry to home. The password which is entered is compared with the predefined password. 0 to 9 ii. If the entered password is correct then the system opens the door by rotating door motor and displays the status of door on lcd.

All the processing s will be done by 8051 microcontroller. It is a simple embedded system with input from the keyboard and the output being actuated accordingly. This system demonstrates a password based door lock system using 8051 microcontroller wherein once the correct code or password is entered the door is opened and the concerned person is allowed access to the secured area. In our diy digital lock system 8051 89c51 89c52 is our intelligent unit.

It will provide keyless entry. We type the password using keypad which is attached with the system. Give the flexibility to the user to change or reset the password in case the user forgets that combination. There are many types technologies available to secure our place like pir based security systems rfid based security system laser security alarms bio matrix systems etc.

Password based door lock system using 8051 microcontroller traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system. Working of password based door locking system with 8051 when power supply is turned on a message enter your password is displayed on lcd. This project can be used in offices companies also at home. If the person attempting to open the door enters a wrong password then the microcontroller switches the alarm for further course of action.

User will enter the password using the keypad. Lock the door by using password. Electronic code lock using 8051 microcontorller security is a major concern in our day to day life and digital locks have become an important part of these security systems. To give user more secure yet cost efficient way of door locking system.

Password based door lock system using 8051 microcontroller circuit design uses five major components a microcontroller l293d motor driver a dc motor a 4ã 4 lcd are connected to p3 0 gnd and p3 2 pins respectively. The main component in the circuit is 8051 controller. Objective increase the security level to prevent an unauthorized unlocking of the door. These techniques are an integration of mechanical and electronic devices and highly intelligent.

Again if another person arrives it will ask to enter the password. If password does not match door remains closed and a message wrong password access denied is displayed on lcd. In this way a simple door lock system can be implemented with the use of a microcontroller. Atmega based garage door opening.

Various keys of keypad are as following i.
