This module produces an digital output based on the humidity of the local environment. Whether it be a Weather station, greenhouse monitor or other project you will be able to trigger devices when a certain amount of water is in the air.
As a standard module for humidity detection, Arduino development does not require a library but instead readings can be read from the output pin. Simply on reaching the set threshold the output will be driven LOW. This opens up the opportunity for an interrupt based program to cut down on power consumption while waiting to hit the threshold.
