5V 12V photosensitive resistance sensor plus relay module light control switch without detection (12V)

Light detection, brightness detection, potentiometer can be adjusted to detect the brightness of the valve point, with its own relay, can do a variety of brightness detection switch. Using the photoresistor to induce the intensity of light, with its own relay, directly control the load Adjust the sensitivity with the potentiometer. Set the start relay threshold by adjusting the potentiometer. When it is brighter, the module relay pulls in. When the threshold is dark, the relay is disconnected. Working voltage 5V/12V Output form: load directly connected to AC 220V 10A or DC30V 10A
