Design And Construction Of A Smart Loop Burglar Alarm

ABSTRACT

Simple loop burglar alarms sound whenever the loop breaks. What if a clever thief comes to know of the working of this alarm? He may simply short the loop by using some other conductor and then cut the shorted portion of the loop without any problem. Here is the circuit of a smart loop burglar alarm that overcomes this drawback by using a sensing resistor (R) in the loop.

This circuit is built around quad op-amp LM324 and a few discrete components. Two op-amps of the LM324 are configured as voltage comparators.
