Humidity sensor and humidity control humidity / humidity switch relay module Arduino

Detailed Product Description

Purpose:

 

Humidity testing, humidity sensor, humidity testing, with relay output, direct control of power related equipment

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 bit detection threshold

4, the sensor interface can be installed pin, plus humidity sensor with leads;

5, circuit board external dimensions: 50x26mm, thickness 19mm, 3mm bolts with four holes for easy installation

 

 

Electrical 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:

 

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 is equivalent to a dual-control switch, relay coil power, often beginning with common terminal conduction, no electricity, the common and normally closed terminal conduction;
