LDR Photosensitive Sensor Module

Description

The LDR Photosensitive Sensor Module is a highly sensitive light detection sensor based on an LDR (Light Dependent Resistor) and LM393 comparator chip. It allows microcontrollers to detect ambient brightness and light intensity efficiently. The sensor provides both analog and digital outputs, making it versatile for automatic light control, day/night detection, and other light-sensitive projects.

This module operates within a voltage range of 3.3V – 5V DC, making it compatible with Arduino, Raspberry Pi, ESP8266, ESP32, and other microcontrollers. It features a signal output indicator LED that provides visual feedback when light intensity changes. The built-in potentiometer allows users to adjust sensitivity, making it ideal for automatic brightness control applications.

With a compact design and mounting hole, this module is easy to integrate into smart lighting, home automation, robotics, and IoT projects. The output options (analog A0 & digital D0) provide flexibility, enabling precise light intensity measurement (A0) or binary light detection (D0) for efficient automation.
