Android Based Door Access Control System

Abstract

This project is developed for the users to monitor and control the operation of a door through Mobile. There are two units. One in the office and the other in the user area. In the Office, a microcontroller kit is connected with a Bluetooth module. In the user area, a microcontroller kit is connected with an android application and LCD display. The microcontroller kit in the Office operates the Mobile to call the user line. The user kit receives the message and according to that microcontroller sends signal through the Mobile. In the other side, the Bluetooth module receives the signal and the signal is converted to digital signal and given to the microcontroller. According to the signal, the microcontroller sends signal to the door through relay. It uses PIC16F77A (28 pin Micro controller). he micro controller program is written in assembly language.
