LDR Light Sensor Module

The LDR light sensor module is designed to detect ambient light intensity using a light dependent resistor. The resistance of the LDR changes according to the amount of light falling on its surface allowing the module to measure variations in light levels.

This module is widely used in automatic lighting systems light detection circuits and environmental monitoring applications. It provides both analog and digital output signals and includes an adjustable sensitivity control for setting the detection threshold. The compact design allows easy interfacing with microcontrollers and embedded electronics systems.
