LDR & Laser Based Security System DIY STEM KIT Science Project Model (Assembled) – 100% Tested

Please Note we are only providing kit we marked as ACTUAL PRODUCT, project shown customer needs to do at there own we just provide reference.

Abstract:

The LDR & Laser Based Security System DIY STEM KIT is an innovative security solution that combines light-dependent resistors (LDR) and laser technology to detect unauthorized access. Designed for DIY electronics projects, this system triggers an alarm whenever the laser beam is disrupted, providing a simple yet effective tripwire security mechanism.

The core component of the system, the LDR sensor, detects changes in light and darkness when the laser beam is interrupted, adjusting its resistance to send signals to a connected buzzer. This project is a perfect example of basic automation and security principles, allowing students and enthusiasts to explore electronics, robotics, and automation concepts in a hands-on manner.

This kit can operate as a standalone security system or as part of larger automation setups, making it ideal for homes, offices, banks, lockers, and other areas needing intrusion detection.
