Humidity sensitive switch relay Module humidity controller sensor for Arduino
습도 센서 5V 릴레이 모듈 HR202
HR202 습도센서를 이용한 릴레이 모듈입니다.
1 humidity sensor quality HR202;
2 the comparator output to directly drive relays, 220V AC or other devices;
3 adjust the temperature distribution bit detection threshold;
4 the sensor interface can be installed pin plus humidity sensor with leads;
5 circuit board Dimensions: 50x26mm, 19mm thick, has four 3mm fixed bolt hole for easy installation.
1 Supply voltage: 5VDC (the default hair 5V current: greater than 150mA;
2 Maximum load: 250V 10A AC or 30V 10A DC, less than the power can be used.
1 Humidity sensor is most sensitive to the ambient humidity generally used to detect the humidity of the surrounding environment;
2 modules in the ambient humidity exceeds the set threshold, the relay together, public end is often the beginning connected,
when the outside ambient humidity is below the set threshold, the relay is switched off, the public side and normally closed end turned on;
3 the public side, normally open, normally closed three ports, the equivalent of a dual-control switch, relay coil power, public end and often the beginning of conduction, radio, public end normally closed terminal conduction.
