XH-M131 DC 12V Light Control Switch Photoresistor Relay Module | Automatic Light Sensor Relay Board 10A

XH-M131 DC 12V Light Control Switch Photoresistor Relay Module | Automatic Light Sensor Relay Board 10A 

The XH-M131 DC 12V Light Control Switch Photoresistor Relay Module is an automatic light sensing relay board designed to control electrical devices based on brightness level. The built-in photoresistor sensor detects light intensity, and the relay turns ON or OFF automatically according to the set threshold.

The brightness level can be adjusted using the onboard potentiometer, allowing precise control for different lighting conditions. This module is widely used in automatic street lights, smart home systems, industrial automation, Arduino projects, IoT systems, and DIY electronics.
