LM393 LDR Light Sensor Module With Digital Output - 3 Pin
The LM393 LDR Light Sensor Module is a simple and reliable solution for detecting ambient light intensity in electronic and microcontroller-based projects. Built around a Light Dependent Resistor (LDR) and the LM393 voltage comparator IC, this module provides a digital output that changes state based on light levels.
The onboard adjustable potentiometer allows users to set the light detection threshold, making it easy to customize sensitivity for different environments. With its 3-pin interface (VCC, GND, DO), the module connects effortlessly to popular platforms such as Arduino, ESP32, Raspberry Pi, and other microcontrollers.
