Harga Untuk 1 Pcs

Spesifikasi:
Use:
Humidity detection, humidity sensor, ambient humidity detection, with relay output, direct control of related equipment power supply

Module features:
1, using high quality HR202 humidity sensor ;
2. The comparator output directly drives the relay and connects to 220V AC or other equipment;
3, with potentiometer to adjust the temperature detection threshold
4, the sensor interface can be equipped with a pin, plus a wet sensor with lead;
5, the circuit board dimensions: 50x26mm, thickness 19mm, with 4 3mm fixing bolt holes for easy installation

Electrical parameters:
Supply voltage: 5VDC
Maximum load: 250V 10A AC or 30V 10A DC, less than this power can be used

Module instructions:
1. The humidity sensor is most sensitive to environmental humidity and is generally used to detect the humidity of the surrounding environment;
2. When the ambient humidity exceeds the set threshold, the relay is closed, and the common end is connected to the normally open end. When the ambient humidity 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 is 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;
