Password Based Door Locking System Using 8051 Program

User can change this password anytime he she wish using a keypad.

Password based door locking system using 8051 program.

How to design circuit of password based door lock system. 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. This digital door lock is simply a password based electronic code lock designed using 8051 micro controller a keypad and a 12 volt dc relay. Password based door lock system using 8051 microcontroller is a simple project where a secure password will act as a door unlocking system.

All the processing s will be done by 8051 microcontroller. In our diy digital lock system 8051 89c51 89c52 is our intelligent unit. So a digital code lock can secure your home or locker easily. In this project we will learn how to make the password based security system using arduino keypad.

Video of the project. In this article we have designed a simple digital door lock using 8051 which can be used as a security checking system to limit access to an area room only for certain individuals with the password. The main concept behind this project is a door latch opening using a password entered through the keypad. Program of password based door locking system with 8051 circuit diagram of password based door locking system with 8051 protious simulation file.

Password based security system using arduino keypad. As thefts are increasing day by day security is becoming a major concern nowadays. Here at89c51 microcontroller is used and it is an 8 bit controller. Projects on password based door lock system using microcontroller april 21 2014 by tarun agarwal 40 comments the basic requirement of security can be achieved by designing electrical or mechanical locks that are designed with one or a few keys but for locking a big area many locks are required.

Password based door lock circuit design uses five major components a microcontroller a relay a dc motor a 4 3 matrix keypad and a lcd. Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system. This controller requires a supply voltage of 5v dc.
