Ldr Burglar Alarm at Matthew Langford blog

Ldr Burglar Alarm. Also known as photoresistor its resistance varies with the intensity of light falling on it. Today i am going to make a circuit of security alarm with ldr. In this tutorial, we are going to demonstrate a circuit of a laser security alarm system that will detect any irregular activity and will produce sound using a buzzer. In this project, we will use a laser and an ldr to radiate light in a straight line. So, in this tutorial, we. If the ldr is not able to detect the laser, the buzzer will alert us that somebody crossed or blocked the laser. When the laser beam is interrupted, the system triggers an alarm and activates an led, alerting you to the possible presence of an intruder. Our intruder alarm works using an ldr (light dependent resistor). This musical light alarm circuit is very simple, uses only 7 components, a ldr and a 3.6 v battery or 3 x 1.2 volts rechargeable batteries. The ldr can detect the laser light if someone crosses it which means the laser light will be blocked. This project utilizes a simple yet effective combination of a laser beam, an ldr (light dependent resistor), a 555 timer ic, a relay, an led, and a buzzer to create an intrusion detection solution. Whenever the laser got interrupted, it will sound an alarm to make you alert that someone has invaded. This laser security alarm circuit uses two bc548 npn transistors as a switching device. Its resistance decreases with increase in light. Since the ldr is connected to the base terminal of the q2 transistor through the.
