Password Door Lock Using 8051

It is a simple embedded system with input from the keyboard and the output being actuated accordingly.

Password door lock using 8051.

Design and implementation of embedded password based security door lock system using 8051 microcontroller article pdf available october 2017 with 502 reads how we measure reads. This circuit operates on the principle of microcontroller interfacing. The main component in the circuit is 8051 controller. These techniques are an integration of mechanical andelectronic devices and highly intelligent.

In this project 4 3 keypad is used to enter the password. Password based door lock system using 8051 microcontroller final report. Working of password based door locking system with 8051 when power supply is turned on a message enter your password is displayed on lcd. It provides control to the actuating the load.

The password is stored in the eprom so that we can change it at any time. Predefined hard coded password is downloaded in the code. User have to enter the code. If the entered password is correct then the system opens the door by rotating door motor and displays the status of door on lcd.

If password does not match door remains closed and a message wrong password access denied is displayed on lcd. To overcome this we design rfid password and otp based door lock system using 8051 microcontroller. All the processing s will be done by 8051 microcontroller. This is a simple password based door locking system circuit designed using 8051 microcontroller.

If the code matches the predefined hard coded code lock will open up and user can enter the room. The microcontroller based door locker is an access control system that allows only authorized person to access a restricted area the system is fully controlled by the 8 bit microcontroller 8051 which has a 2kbytes of rom for the program memory. Password based door lock system using 8051 microcontroller circuit design uses five major components a microcontroller an l293d motor driver a dc motor a 4 4 matrix keypad and a 16 2 lcd. We type the password using keypad which is attached with the system.

The password which is entered is compared with the predefined password. Here an at89c52 microcontroller is used and it is an 8 bit controller. This controller requires a supply voltage of 5v dc. A numeric password is hard coded in the 8051 microcontroller code.

Password based door lock system using8051 microcontrollertraditional lock systems using mechanical lock and key mechanism are being replaced by newadvanced techniques of locking system.
