15 Laser Security Alarm System Circuit Diagram. Current firmware of this system presents interactive control system through the rs232 interface. This is a project of a very smiple laser security alarm circuit.
Your laser security alarm system is now ready! When an intruder walks past the device, the ir beam is cut and thus the alarm is activated. Security alarm using ir led and phototransistor.
Launched in 1996, the 3000 was developed from the laser 2.
15 Laser Security Alarm System Circuit Diagram. The circuit of an inexpensive and highly secure electronic security system is explained below. Attach high reset switch : Laser security alarm circuit produce highly audible buzzer beep sound when the laser light blocked. Below is a circuit design diagram which illustrates the flow of a laser alarm system.
