Module Description
1, humidity sensor module is very sensitive to humidity, generally used to detect ambient humidity;
2, through the potentiometer adjustment, you can change the humidity detection threshold That control humidity , Such as the need to control humidity of 60%, the corresponding module in the humidity adjusted its green light, DO output is high, the humidity falls below the set value, the output high, green light does not shine;
3, DO output can be And is directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting the humidity changes in the environment;
4, DO output of the relay module can directly drive the shop, which can be composed of a humidity switch, control-related device to operate at a suitable environment;
