LDR Light Sensor Module - (Compatible with Arduino)

LDR Light Sensor Module with Analog & Digital Output for Arduino

The LDR Light Sensor Module is an essential component for detecting ambient light and measuring light intensity in your electronic projects. Designed to be fully compatible with Arduino and other microcontrollers, it offers versatile integration. This module provides both analog (A0) and digital (D0) outputs, allowing for precise light measurement and threshold-based switching. Its digital output goes high in bright light and low in darkness, making it ideal for simple light-sensitive applications. Sensitivity can be easily fine-tuned using the onboard potentiometer to meet specific project requirements. Equipped with an LM393 comparator chip, it ensures stable performance and reliable light detection. The compact PCB design includes convenient mounting holes for easy and secure installation. It's perfect for smart lighting, automation systems, day/night detection, and various embedded projects.
