  • 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 door lock
    system. We want to utilize the electronic technology to build an integrated and fully customized
    home security system at a reasonable cost. We hope this project will be useful in keeping thieves,
    dacoits and other sort of dangers at bay.
    By using this system we can unlock the door by using pre-decided password, increase the
    security level to prevent an unauthorized unlocking. In case the user forgets the combination of
    password this system give the flexibility to the user to change or reset the password. This
    automatic password based lock system will give user more secure yet cost-efficient way of
    locking-unlocking system.
    Firstly the user combination will be compared with prerecorded password stored in the system
    memory. Our system will allow the user to go for certain number of wrong combinations before
    the system will be temporarily disabled. But if user combination matches with the password, the
    door will be unlocked. The same password can be used to lock the door. This system will give
    the user an option to reset his own password if he wants.
