Smart Loop Burglar Alarm
As long as the cycle is interrupted, an anti-theft alarm will sound. But what if there is a thief who understands this principle? Usually, the operation of the thief may be to shorten the loop conductor by using some other tools, thereby cutting off the short-circuited part of the loop. Here is the circuit of the smart loop anti-theft alarm, which overcomes this shortcoming by using the inductor, which is the resistance (R) in the loop.
