Module instructions
1. The humidity sensor module is 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 threshold of humidity detection (ie, control the humidity value). If you need to control the ambient humidity to 60%, the module will adjust its ambient humidity to its green light, and DO will output high power. Flat, below this set humidity value, the output is high level, the green light is not bright;
3. The DO output terminal can be directly connected to the single-chip microcomputer, and the high-low level is 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 the store, so that a humidity switch can be formed to control the related equipment to work in a suitable environment;

5, the small board analog output AO can be connected with the shop AD module, through AD conversion, you can get more accurate values ​​of environmental humidity;
