LDR Based darkness Detection DIY Experiments Science Project Model STEM KIT Ready (Assembled), 100% Tested

Product Overview

The LDR-Based Darkness Detection DIY Kit is an innovative and educational science project kit designed to detect the absence of light using an LDR (Light Dependent Resistor), LM393 comparator IC, and a relay. It’s ideal for students, hobbyists, and electronics enthusiasts who want a ready-to-use, 100% tested project for STEM experiments.

How It Works

This kit uses the LDR to sense light intensity. When light is absent, the LDR stops conducting, triggering the piezo buzzer to sound an alarm. The LM393 IC acts as a comparator to detect the change and activate the relay, ensuring seamless circuit performance.
