Description:
This module is the 12 v power supply stable version, with no time delay function, relay and matt, there is light off. photosensitive resistor module is the most sensitive to ambient light, usually used to detect ambient light brightness.the module in the ambient light when the threshold is set, the relay pull in, the public end and the beginning of the switch, when the ambient light is set at the threshold value, the relay is off, the common end and the normally closed end of the switch. the public side, normally open, normally closed three ports is equivalent to a double control switch, when the relay coil is power, the public end and often start conduction, no electricity, the common end and the normally closed side conduction.
