Laser Light Security System Circuit Diagram. 0 2 laser light security system using arduino with alarm. This is a project of smiple laser security alarm circuit.
The laser pointer is used as the source of light beam. Your laser security alarm system is now ready. Normally laser door alarm circuit will have two sections.
This video just to show how to make laser light security at home by using two transistor three resistance one photo resistance ldr and one led.
This is a project of smiple laser security alarm circuit. Laser door alarm is based on the interruption of laser beam. As soon as you connect the battery the l e d and buzzer will come on if you re in a dark room. The circuit can be used as a laser door alarm laser motion detector laser proximity sensor trip wire alarm and for other simple home security purposes.
