Hot selling HR202 humidity sensitive switch relay module humidity switch module humidity sensor controller DC5V quality online

Product Purpose

Humidity detection, humidity sensor, environmental humidity detection, with relay output, directly controlling the power supply of related equipment

Product Features

1. Adopting high-quality HR202 humidity sensor;

2. The comparator output directly drives the relay and is connected to 220V AC or other devices;

3. Adjust the temperature detection threshold with a potentiometer

4. The sensor interface can be equipped with a pin and a humidity sensitive sensor with lead wires;

5. The external dimensions of the circuit board are 50x26mm, 19mm thick, and equipped with 4 3mm fixing bolt holes for easy installation

Product Electrical parameters

Power supply voltage: 5VDC or 12VDC (default output 5V, please leave a message if 12V is required)

Current: greater than 150mA

High load: 250V 10A AC or 30V 10A DC, both below this power can be used

Product usage instructions

1. Humidity sensors are sensitive to environmental humidity and are generally used to detect the humidity of the surrounding environment;

2. When the environmental humidity exceeds the set threshold, the relay is closed and the common terminal and normally open terminal are connected. When the external environmental humidity is below the set threshold, the relay is disconnected and the common terminal and normally closed terminal are connected;

3. The common terminal, normally open, and normally closed ports are equivalent to a dual control switch. When the relay coil is powered, 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;
