🌞 Digital LDR Light Sensor Module – Easy Light Detection for Arduino, ESP32, and IoT Projects

The Digital LDR Light Sensor Module provides a simple and effective way to detect ambient light levels. Utilizing a light-dependent resistor (LDR) in combination with a comparator IC and adjustable potentiometer, this module outputs a digital HIGH or LOW signal based on the ambient light intensity.

It’s commonly used in light-activated projects such as automatic lighting systems, garden lights, alarms, or basic robotics, where a device needs to respond to changes in light conditions. With its breadboard-friendly 3-pin interface (VCC, GND, OUT), this module is easy to integrate with Arduino, ESP32, ESP8266, Raspberry Pi, and other microcontrollers.
