ITEM NAME:Relay Module Moisture Humidity Sensor Control Switc A6U3 Relay Module Moisture Humidity Sensor Control Switc A6U3 The comparator outputs directly drive relays , or other devices connected to 220V AC Adjust the temperature distribution position detection threshold The sensor interface can be installed pin , plus humidity sensor with leads The circuit board dimensions as : 50x26mm/1.97 x 1.02 inch thickness:19mm/0.75 inch,has four 3mm bolts holes for easy installation Parameters: Supply voltage : 5VDC ( default hair 5V Current : more than 150mA Maximum load : 250V 10A AC or 30V 10A DC , this power can be used by small Module for use: The humidity sensor most sensitive to environmental humidity , generally used to detect ambient humidity ; 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; 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 ; material:plastic colour:blue packing:1* Humidity Switch Relay Module Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm..The sensor interface can be installed pin, plus humidity sensor with leads. Module for use Maximum load : 250V 10A AC or 30V 10A DC, this power can be used by small.
