5V 12V Light Photoswitch Sensor Switch LDR Photoresistor Relay Module Light Detection Photosensitive Sensor Board Net Weight:16g Working Voltage: 5V or 12V Load Power: AC 250V/10A, DC 30V/10A ur fixed bolt hole for easy installation Instructions 1. photoresistors module is most sensitive to ambient light, generally used to detect the brightness of the ambient light. 2. when the ambient light is darker than the threshold value is set, the relay is energized, the common terminal and the normally start is turned on, when external ambient light is brighter than the set threshold value, the relay is switched off, the common terminal and the normally closed end connected. 3. the public side, normally open, normally closed three ports, the equivalent of a dual-control switch, relay coil power, public end and often the beginning of conduction, radio, public end normally closed terminal conduction.
