Detect ambient light levels with the Photoresistor (LDR) Light Sensor Module. This compact module combines a Light Dependent Resistor (LDR) with an LM393 voltage comparator, providing both analog and digital outputs for easy integration into electronic projects. The onboard potentiometer allows you to adjust the light detection threshold, making it ideal for automatic lighting systems, smart home automation, solar tracking, light intensity monitoring, and IoT applications.
Compatible with Arduino, ESP32, ESP8266, STM32, Raspberry Pi, and other popular development boards, this sensor is perfect for students, hobbyists, and embedded developers looking to build responsive light-based projects.
