Four modules using the instructions

A humidity sensitive resistor module on the ambient humidity is the most sensitive, generally used to detect the humidity of the surrounding environment.

2 module in the ambient humidity of less than a set threshold, the DO output port high, when the outside ambient humidity exceeds the set threshold, the module D0 output is low;

Board digital outputs D0 can be directly connected with the microcontroller, the microcontroller to detect high and low, and thus to detect the humidity change;

4 board digital output DO OUR relay module can directly drive, which can form a wet control switch;

5 small plates analog output AO OUR AD module connected through the AD converter, you can get more accurate ambient humidity value;
