The DC 12V Light Control Switch Module with a built-in photoresistor (LDR) is a smart relay module that automatically switches devices on or off based on ambient light levels.
The DC 12V Light Control Switch Module with a built-in photoresistor (LDR) is a smart relay module that automatically switches devices on or off based on ambient light levels. Ideal for energy-saving applications such as street lights, garden lamps, or solar-powered systems, this module activates a connected load when it gets dark and deactivates it during daylight.
Simple to use and compatible with various loads, the module offers plug-and-play functionality for automation projects, hobby electronics, and lighting control systems.
