Laser Security System
Laser based security system that use light sensor to sense some one cross the boundary
Overview
The system uses a laser light directed continuously toward a light sensor such as an LDR. Under normal conditions, the laser beam falls directly on the sensor. When a person crosses the protected area, the beam is interrupted, causing a change in the sensor’s resistance. This change is detected by the circuit and triggers an alert.
Key Features
- Low cost and simple design
- Fast intrusion detection
- Low power consumption
- Easy to install and maintain
