Abstract : Security is primary concern for every one. This Project describes a design of effective security alarm system that can monitor the house with different sensors.

Unauthorized access, IR detection and LDR detection can be monitored by the status of each individual sensor and is indicated with an LED.

The burglar alarm is built around the 8051 microcontroller from Atmel. This microcontroller provides all the functionality of 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.
