For ambient humidity detection, high quality humidity sensor with relay output to direct control of related equipment power
1, Adopt high-quality HR202 humidity sensor;2, The comparator output directly the driver relays,connecting with 220V AC or other equipment;3, With a potentiometer to adjust the detection threshold for temperature
4, Pinheader can be installed with the sensor interface,which can connect with the humidity sensor with the lead wire
5, The board dimensions: 50*26*19mm, with 4 3mm fixed bolt holes for easy installation
Supply Voltage: 5VDC
Maximum Load: 250V/10A AC or 30V/10A DC,or less than this power
1, Humidity sensor is most sensitive to environmental humidity, generally used to detect the ambient humidity;2, The relays pull in, so the common end and normally open end connect when the ambient humidity exceeds the set threshold;3, The relays break off, so the common end and normally closed end connect when the ambient humidity is below the set threshold.4, Common end, normally open end & normally closed end is equivalent to a dual control switch.---The common end and the normally open connect when the relay live electricity ;---The common end and normally closed end connect when the relay is out of electricity.Package list
1 x Humidity Sensor Switch.
