Details

This relay combines a photoresistor with its own relay and adjustable sensitivity to control any desired device based on the amount of light the photoresistor is exposed to.

Basic Instructions

1. The photoresistor module is most sensitive to ambient light and is generally used to detect the brightness of ambient light.
2. When the ambient light exceeds the set threshold, the relay is closed, and the common end is connected to the normally open end. When the ambient light is lower than the set threshold, the relay is disconnected, and the common end is connected to the normally closed end;
3. The common end, normally open, normally closed three ports are equivalent to a dual control switch, when the relay coil is powered, the common end is open to the normally open end, when there is no electricity, the common end and the normally closed end are turned on;
