ANTI-THEFT ALARM SYSTEM
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.
SOFTWARE AND HARDWARE TOOLS:
- Keil compiler
- Microcontroller AT89S52.
- IR sensors
