DESIGN AND IMPLEMENTATION OF PASSWORD BASED ACCESS CONTROL WITH INTRUDER ALERT SYSTEM

DESIGN AND IMPLEMENTATION OF PASSWORD BASED ACCESS CONTROL WITH INTRUDER ALERT SYSTEM

ABSTRACT

The necessity of a low cost electronic home security system designed in co-ordination with other security measures is always there in our society to reduce the risk of home intrusion. Keeping this problem in mind, we are working on a project on automatic password based control system which is technology is based on access control system. We want to utilize the electronic technology to build an integrated and fully customized home security system at a reasonable cost.

This is the design and construction of access control system which is use in locking or switching on and off a password based design through a microcontroller (at89s52) for example creating a password system to make led on and off when the write password is entered
