DO small plate switch digital output interface (0 and 1)
AO-board analogue output interface ur modules for use
the hygristor module is most sensitive to the ambient humidity, generally used to detect the humidity of thesurrounding environment.
module when the environmental humidity reach the threshold value is set, DO port output high, when the humidity exceeds the threshold value is set when the external environment, the module D0 output is low;
small plates digital outputs D0 can be directly connected with the microcontroller, microcontroller to detect high and low, and to detect changes in environmental humidity;
board digital output DO OUR relay module can directly drive, which can form a wet control switch;
small plates analogue output AO OUR AD module connected through the AD converter, you can get more accuratevalues of the ambient humidity;
