ELECTRONIC EYE WITH SECURITY DIALUP

Security is primary concern for every one. This Project describes a design of effective security alarm system that can monitor the predefined area with different sensors. Unauthorized access, Fire accident, wall braking, IR detection, and fire detection can be monitored by the status of each individual sensor and is indicated with an LED. This security system works perfectly all the time i.e., whether some one is present in the area or not.

The burglar alarm is built around the 8051 micro controller from Atmel. This micro controller provides all the functionality of the burglar alarm. A maximum of 8 sensors can be connected to the burglar alarm. A power supply voltage of +5 VDC is available for each sensor at the corresponding wiring terminals.

LEDs indicate the status of the corresponding sensors. When the alarm has been activated, the LED of the sensor that caused the alarm will light up, or flash in the event of a cable failure. LCD display is provided in this project so as to give the information about the sensor triggered.
