HR202 HC-13 12V Humidity Relay Module Sensor Kelembaban Udara

Humidity detection, humidity sensor, environmental humidity detection, with relay output, direct control of related equipment power

Module Features:
1, the use of high quality HR202 humidity sensor;
2, the comparator output directly drive the relay, then 220V AC or other equipment;
3, with the potentiometer to adjust the temperature detection threshold
4, the sensor interface can be equipped with pin, plus lead of the humidity sensor;
5, circuit board Dimensions: 50x26mm, thickness 19mm, with 4 3mm fixed bolt holes, easy to install

Electrical parameters:
Supply voltage: 5VDC or 12VDC (default to 5V, need 12V please message)
Current: greater than 150mA
Maximum load: 250V 10A AC or 30V 10A DC, less than this power can be used

Module Instructions:
1, humidity sensor is most sensitive to environmental humidity, generally used to detect the humidity of the surrounding environment;
2, the module in the ambient humidity exceeds the set threshold, the relay pull, the common side and normally open end, when the ambient humidity below the set threshold, the relay is off, the common end and normally closed end;
3, the common, normally open, normally closed three ports is equivalent to a dual control switch, the relay coil has electricity, the common and often open at the beginning, no electricity, the common and normally closed end conduction;
