Introduction
Humidity-sensitive sensor most sensitive to humidity, generally used for detection of humidity of the surrounding environment;
Module in the ambient humidity exceeds the set threshold value, the relay sucks and shuts, common Terminal and start connecting, and when relative humidity falls below the specified threshold value, the relay disconnect, common end and closed-end connected;
Common, normally open, normally closed three ports as a dual-control switch, relay coil is electrified, the public side and start conducting, when there was no electricity, the common end and closed-end pass;
Features
The use of high quality HR202 humidity sensor;
The comparator output direct drive relays, 220V AC, or other device;
Distribution adjusting temperature detection threshold
Sensor interface can be mounted pin, plus humidity sensor with wire;
Circuit board dimensions are: 50x26mm, 19mm, with 4 3mm bolt holes for easy installationElectrical
