LDR Light Sensor Module with Analog and Digital Output (LDR Sensor Module)

The LDR Light Sensor Module is designed to detect ambient light intensity using a Light Dependent Resistor (LDR). 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. It provides both analog and digital outputs, making it suitable for automatic lighting systems, light detection circuits, environmental monitoring, and embedded electronics projects.
