HR202 5V Humidity Switch Sensor Relay Module Sensitive Humidity Controller Sensor Module Direct drive relay

Origin:CN(Origin)
Smart home platform:NONE
Model Number:HR202 humidity switch sensor module
Certification:NONE

Humidity detection, humidity sensor, environmental humidity detection, with relay output, directly control the power supply of related equipment
Module features:
1. Use high-quality HR202 humidity sensor (the stock is a blue shell);
2. The output of the comparator directly drives the relay and connects to 220V AC or other equipment;
3. The power distribution positioner adjusts the temperature detection threshold
4. The sensor interface can be equipped with pin headers and humidity sensors with lead wires;
5. The external dimensions of the circuit board are: 50x26mm, 19mm thick, with 4 3mm fixing bolt holes for easy installation
Electrical parameters:
Power supply voltage: 5VDC (default 5V current: more than 150mA
Maximum load: 250V 10A AC or 30V 10A DC, less than this power can be used
Module instructions:
1. Humidity sensors are the most sensitive to environmental humidity, and are generally used to detect the humidity of the surrounding environment;
2. When the module's ambient humidity exceeds the set threshold, the relay is closed, and the common terminal is connected to the normally open terminal. When the ambient humidity is lower than the set threshold, the relay is turned off and the common terminal is connected to the normally closed terminal;
3. The common terminal, normally open and normally closed, is equivalent to a dual-control switch. When the relay coil is energized, the common terminal is connected to the normally open terminal, and when there is no power, the common terminal is connected to the normally closed terminal;
Package Included:
Humidity sensor plus 1 relay module, with humidity resistance
