Name : laser home security system project/laser security alarm working model/Inspire award project

How It Works : Laser Beam Setup: A laser torch emits a beam that travels across the area by reflecting off three strategically placed mirrors (glasses). This configuration creates a continuous laser barrier around the perimeter of a model house or any area you wish to secure.

LDR Detection : The laser beam ultimately hits an LDR module, which is sensitive to light. As long as the laser beam is unbroken and falls on the LDR, the system remains in a passive state, with no alarm triggered.

Relay and Buzzer Activation : The LDR is connected to a single-channel relay module that controls a 9V buzzer. If the laser beam is interrupted, the LDR detects a change in light intensity, signaling the relay to activate the buzzer. This results in an audible alarm that warns you of the potential intrusion.

Unauthorized Entry Alert : The alarm is designed to activate whenever there is an obstruction in the laser path, such as someone entering the secured area without permission. This feature provides a simple yet effective means of safeguarding your space.
