1 Pieces - Humidity Switch Relay Module Humidity Controller C9

Description

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;
