Description

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.

Key Features

Fully Assembled & Tested: Ready to use straight out of the box.
Easy-to-Follow Resources: Includes circuit diagrams, PCB layouts, and video tutorials.
Reliable Components: Features high-quality LDR, LM393 IC, and relay for accurate detection.
Customizable: Adjustable sensitivity using the R2 variable resistor.
Educational Value: Perfect for learning electronics, automation, and light-sensing technology.

Applications

Electronics Experiments: Ideal for understanding light sensors and comparator circuits.
Automation Projects: Use in light-activated systems, alarms, and other automated circuits.
School/College Projects: Ready-to-submit science projects with clear documentation.
Robotics and DIY Kits: Widely used in robotics and automation experiments.
