LDR Sensor Module Light Dependent Resistor

The LDR Sensor Module is a simple yet effective component for detecting ambient light levels. It uses a Light Dependent Resistor (LDR) that changes resistance with light intensity, allowing microcontrollers to sense brightness and take actions based on it.

This module is widely used in Arduino and IoT projects for building automatic lighting systems, solar trackers, smart garden systems, and line-following robots. The module provides an analog output for light level detection and a digital output using an onboard comparator and potentiometer.

It is easy to use with Arduino, ESP32, Raspberry Pi, and other microcontrollers.
