LDR Light Sensor Module

The LDR (Light Dependent Resistor) Light Sensor Module is a simple and widely used sensor that detects ambient light intensity. It uses a photoresistor whose resistance changes according to the amount of light falling on its surface. The module provides both analog and digital outputs, making it suitable for light-sensitive automation, smart lighting systems, and DIY electronics projects.
