Size Chart: 1. Humidity sensor is most sensitive to environmental humidity, generally used to detect the humidity of the surrounding environment. 2. When the environmental humidity exceeds the set threshold, the relay is pulled in and the common end is connected with the usual start. When the ambient humidity is lower than the set threshold, the relay is disconnected and the common terminal is connected to the normally closed terminal. 3. Common end, normally open, normally closed, the 3 ports are equivalent to a double control switch, when the relay coil is power, the common end and common start, without electricity, the common end and the normally closed end.
