Password Based Door Locking System Using 8051 Program

Video of the project.

Password based door locking system using 8051 program. User can change this password anytime he she wish using a keypad. As thefts are increasing day by day security is becoming a major concern nowadays. 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. 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 locking system. In this project we will learn how to make the password based security system using arduino keypad. Password based door lock system using 8051 microcontroller is a simple project where a secure password will act as a door unlocking system. The main concept behind this project is a door latch opening using a password entered through the keypad.

These techniques are an integration of mechanical and electronic devices and highly intelligent. So a digital code lock can secure your home or locker easily. How to design circuit of password based door lock system. Here at89c51 microcontroller is used and it is an 8 bit controller.

Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system. Program of password based door locking system with 8051 circuit diagram of password based door locking system with 8051 protious simulation file. 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 traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system.

Password based security system using arduino keypad. 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. 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.
