use:
Humidity detection, humidity sensor, environmental humidity detection, with relay output, direct control of related equipment power
Module Features:
1, using high-quality HR202 humidity sensor;
2. The comparator output directly drives the relay and is connected to 220V AC or other equipment;
3.Distribution positioner adjusts the temperature detection threshold
4. The sensor interface can be equipped with pin headers, plus humidity-sensitive sensors with leads;
5. The overall dimensions of the circuit board are: 50m * 26mm * 19mm (length * width * height) with 4 3mm fixing bolt holes for easy installation
Product parameters:
Power supply voltage: 12VDC
Current: greater than 150mA
Maximum load: 250V 10A AC or 30V 10A DC, less than this power can be used
Module use instructions:
1. Humidity sensor is the most sensitive to environmental humidity, and is generally used to detect the humidity of the surrounding environment;
2. When the module's ambient humidity exceeds the set threshold, the relay will be closed, and the common terminal will be connected to the normally open terminal. When the ambient humidity is lower than the set threshold, the relay will be disconnected, and the common terminal will be connected to the normally closed terminal
3. The common terminal is normally open. The normally closed three ports are equivalent to a dual control switch. When the relay coil is energized, the common terminal is normally connected to the normally open terminal. When there is no power, the common terminal is normally connected to the normally closed terminal.
