Module instructions
1. Humidity sensor module is very sensitive to environmental humidity, and is generally used to detect the humidity of the surrounding environment;
2. By adjusting the potentiometer, you can change the humidity detection threshold (ie, control the humidity value). If you need to control the ambient humidity to 60% , the module will adjust the corresponding ambient humidity to its green light, and the DO will output high power. When the humidity is lower than the set humidity value, the output is high and the green light is off;
3. The DO output terminal can be directly connected to the single-chip microcomputer, and the high and low level can be detected by the single-chip microcomputer, thereby detecting the humidity change of the environment;
4. The DO output terminal can directly drive the relay module of our store, which can form a humidity switch to control related equipment to work in a suitable environment
