1 Pieces - Humidity switch Relay Module Humidity Controller Arduino #3102 c9
Package Includes
1 Piece - Humidity sensor
Module Features:
1, Using high-quality HR202 humidity sensor;
2, The comparator outputs directly drive relays, or other devices connected to 220V AC;
3, Adjust the temperature distribution position detection threshold
4, The sensor interface can be installed pin, plus humidity sensor with leads;
5, The circuit board dimensions as: 50x26mm, thickness 19mm, has four 3mm bolts holes
Electrical parameters:
Supply voltage: 12v
Current: more than 150mA
Maximum load: 250V 10A AC or 30V 10A DC,
Module for use:
1, the humidity sensor most sensitive to environmental humidity, generally used to detect ambient humidity;
2, when the module is in the ambient humidity exceeds the set threshold, the relay, often beginning with a common terminal connected, when the ambient humidity is below the set threshold, the relay off, the common terminal and the normally closed terminal connected;
3, common, normally open, normally closed three ports is equivalent to a dual-control switch, relay coil power, often beginning with a common terminal conduction, when there is no electricity, common and normally closed terminal conduction;
