LDR Photosensitive Light Detection Module

Trigger processes based on precise light thresholds with this LDR Sensor Module, a photosensitive light detection board that converts analog LDR readings into a clean digital output using an onboard LM393 comparator IC. It’s ideal for applications like automatic street lights and solar panel charging controllers.

With an adjustable potentiometer to fine-tune sensitivity, this module makes it easy to determine when ambient light crosses a certain threshold to trigger connected processes. Its bolt-hole mounting and indicator LEDs make installation and status monitoring straightforward for any DIY or automation project.

• Operating voltage 3.6V to 5V DC – Compatible with common microcontrollers
• Adjustable sensitivity potentiometer – Fine-tune light threshold detection
• LM393 comparator IC – Converts analog signal to digital output
• Digital output – Simple integration with GPIO pins
