Ldr Security Alarm Circuit Diagram at Carol Guy blog

Ldr Security Alarm Circuit Diagram. Laser security alarm circuit produce highly audible buzzer beep sound when the laser light blocked. In this project, we will use a laser and an ldr to radiate light in a straight line. In this tutorial, we are going to demonstrate a circuit of a laser security alarm system that will detect any irregular activity. Today i am going to make a circuit of security alarm with ldr. This laser security alarm circuit uses two bc548 npn transistors as a switching device. A laser security alarm system using an arduino uno microcontroller, an ldr sensor, and a laser light module is a highly effective and customizable security system. Laser security system circuit diagram in the above circuit diagram, we can see that the npn transistor is acting as a switch whose base is connected to the 10k resistor. Here ldr placed to sense the laser light from the laser diode. The ldr can detect the laser light if someone crosses it which means the laser light will be blocked. Since the ldr is connected to the base terminal of the q2 transistor through the.
