Description:
- Using high-quality HR202 humidity sensor
- 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 : Approx. 5x2.6cm/1.97x1.02 inch, thickness: Approx. 1.9cm/0.75 inch, has four 3mm bolts holes for easy installation
Specification:
- Material: PCB Circuit Board
- Supply voltage : 5VDC ( default hair 5V Current : more than 150mAMaximum load : 250V 10A AC or 30V 10A DC , this power can be used by small
- 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
Package Includes:
1 Piece Humidity Switch Relay Module
