LDR module

Description

The LDR (Light Dependent Resistor) Day-Night Sensor Module is an automatic light control switch designed for use with 110–240V AC mains appliances. It detects the surrounding light intensity using an LDR sensor and switches the connected device ON at night (darkness) and OFF during daytime (light).

This module eliminates the need for manual switching and is widely used in street lighting, outdoor lamps, corridor lights, and energy-saving home automation systems.
