š Product Description
The LDR Sensor Module (Photosensitive Light Detection Module) is a compact light-sensing module designed to detect ambient light levels and provide a digital output based on a user-adjustable threshold. It combines a high-quality Light Dependent Resistor (LDR) with the reliable LM393 comparator IC, making it easy to integrate into Arduino, ESP32, Raspberry Pi, and other embedded systems.
The onboard potentiometer allows users to adjust the sensitivity according to their project requirements. When the surrounding light crosses the preset threshold, the module changes its digital output, making it perfect for automatic lighting, solar energy systems, security devices, robotics, and smart home automation.
Its compact design, indicator LEDs, and simple wiring make it an excellent choice for beginners and professionals alike.
