Generally in our homes and banks we will put our money ,Gold and other expensive items in the lockers. In case if there is no person in the home/bank, there is a chance that an unauthorized person (stealer) may broke the locker and steal your property. There is no guarantee that you will get back your property. Keeping this point in mind i designed a security system which will alert the owner and Cops when unauthorized person opens your locker.
Block diagram:
Working:
When the locker is closed the controller will not send any message to the owner. When unauthorized person opens the door the controller will send a message "Warning: Unauthorized person opened the lock" to the owner ( and also to the police controller room with address if required).
