Question

explain in detail about laser security alarm

Answer 1

Hey mate here is your answer

The basic principle is that the Laser transmitter emits the laser beam and on the opposite side there is the light reciever which recieves the laser beam. If by any means if that laser beam is interrupted or the reciever doesn't recieves the light, the resistance of the reciever increases which decreases the voltage inside the circuit. After that the output becomes low then the corresponding tripper 5 timer gets triggered which automatically triggers the buzzer and the LED light which can be heard as the alarm.

So in home the alarm will be placed in the area where you want security such that in case of home invasions the alarm will be triggered, the laser beam senses the heat emitted by the human body or animal which automatically triggers the alarm system.

Hope this answer will help you!!!
