LDR Light Sensor Module (Photoresistor)

Overview & Features The Imported LDR Sensor Module is a highly versatile and easy-to-use light detection board designed for microcontrollers and DIY robotics. Utilizing a high-quality Light Dependent Resistor (Photoresistor), this module measures ambient light intensity and outputs the data in both digital and analog formats. Equipped with an onboard LM393 dual differential comparator, the module provides a clean, reliable Digital Output (DO) that triggers when the ambient light drops below or rises above a specific threshold. This threshold is fully adjustable via the onboard multi-turn potentiometer. Additionally, the Analog Output (AO) provides a real-time, variable voltage reading relative to the exact light intensity, making it an essential input device for Arduino, Raspberry Pi, and smart home automation projects.
