Bank Locker Security System With Cellphone Alert

Abstract

This project is developed for the users to use a high security locker with auto dialing. It mainly consists of a lock and key, microcontroller unit and telephone circuit. The lock is connected with the locker. A key pad is connected with the microcontroller unit. The signal from the key pad is sent to the microcontroller unit. The microcontroller unit controls a telephone circuit. To open the locker, the user has to give proper security code using the key pad. The microcontroller analyses the code and alerts the user with a green signal to open the door. If he is not an authorized user, the microcontroller sends signal to the controlling unit and there by operating the telephone circuit. The controlling unit makes a call to the particular user. This project gives high security to the user so that un authorized person can not open the locker. The microcontroller used is PIC 16F73 and the microcontroller program is written in assembly language.
