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 bit detection threshold
4. the sensor interface can be installed the pin, plus humidity sensor with leads ;
5. circuit board external dimensions: 50x26mm, thickness 19mm, 3mm bolts with four holes for easy installation

Electrical parameters:

1. Supply voltage: 5VDC or 12VDC ( default hair 5V, please leave a message needs to 12V )
2. Current: more than 150mA
3. Maximum 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 is generally used to detect ambient humidity ;
2. the module in ambient humidity exceeds the set threshold, the relay, normally open end and connected to the public, when the outside ambient humidity is below the set threshold, the relay is switched off, the common and normally closed terminal connected ;
3. common, normally open, normally closed three ports are equivalent to a dual-control switch, relay coil power, often beginning with common terminal conduction, no electricity, the common and normally closed terminal conduction

Package Includes:

1XLM393 Indicator Light 1 Channel Digital Humidity Sensor Relay Module
