LDR Light Sensor Module for Arduino, Raspberry Pi & Smart Lighting Projects

The LDR Sensor Module (Light Dependent Resistor) is an essential light-sensing solution for your electronics projects. It detects ambient light intensity and outputs analog or digital signals, allowing microcontrollers like Arduino, Raspberry Pi, ESP32, and NodeMCU to respond to changes in brightness. This module is perfect for smart lighting, automatic night lamps, sunlight detection, and DIY weather stations.

Compact and easy to integrate, the module comes with an onboard comparator (LM393), offering adjustable sensitivity via a potentiometer. Whether you’re building a smart home system or a solar tracker, this module is a reliable and cost-effective light detection tool.
