Password Based Door Lock System Using 8051 Microcontroller Project Report

Password based door lock system using 8051 microcontroller final report.

Password based door lock system using 8051 microcontroller project report.

In our diy digital lock system 8051 89c51 89c52 is our intelligent unit. Here at89c51 microcontroller is used and it is an 8 bit controller. Password based door locking system. 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.

All the processing s will be done by 8051 microcontroller. Our digital code lock project is a simple electronic number lock system or an electronic combination lock using 8051 which has a preset 5 digit password stored inside the program the system collects 5 digit user input compares the user input with the preset password inside program and if the user input and stored password matches access will be granted by opening the door with the help of relay for a few seconds and closing it automatically after stipulated time. This controller requires a supply voltage of 5v dc. The main concept behind this project is a door latch opening using a password entered through the keypad.

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. 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. 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. These techniques are an integration of mechanical andelectronic devices and highly intelligent.

User can change this password anytime he she wish using a keypad. The password is stored in the eprom so that we can change it at any time. 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. It is a simple embedded system with input from the keyboard and the output being actuated accordingly.

Again if another person arrives it will ask to enter the password. 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.
