About this product
CIRCUIT WITH LASER LIGHT WITH BATTERYThe Laser Alarm Circuit with Laser Light is a simple yet effective security system that works on the principle of light interruption. A laser beam is directed towards a Light Dependent Resistor (LDR). When the beam is continuous, the circuit remains inactive. If the beam is blocked by an intruder or object, the resistance of the LDR changes, triggering a buzzer or alarm. This project is cost-effective, easy to build, and demonstrates the application of basic electronic components in security systems. It is widely used as a school science project and can also be implemented as a basic home security system. • Power Source: DC • Material: Copper • Weight: 0.2
