This project is an anti-theft alarm system using AT89S52 microcontroller. Use of embedded technology makes this closed loop feedback control system efficient and reliable. Microcontroller (AT89S52) allows dynamic and faster control. AT89S52 micro controller is the heart of the circuit as it controls all the functions.
Security
is a major concern for everyone and everywhere. Even a common man tries to
provide security to his wealth, bank account etc.
This project uses the
wireless concept IR to implement this application. The IR transmitters and
receivers will be placed in a fashion that they face each other. That is, the
IR receiver receives the light continuously emitted by the IR transmitter. This
kind of arrangements will be made at the entrance of the confidential rooms. The
outputs coming out from various receivers will be sent to the microcontroller.
Thus
the microcontroller continuously monitors the status of the IR receivers. The
system continuously monitors and immediately activates the alarm system if any
of the sensor trigger. LCD is used to display the status of the sensors.
