Module for use
1, Humidity sensor module is very sensitive to the ambient humidity is generally used to detect ambient humidity;
2, through the adjustment of the potentiometer, detecting the humidity threshold (i.e. control the humidity value) can be changed, such as the need to control the humidity of 60%, the module is then transferred to the green light in the corresponding environment humidity, DO output high level below the set humidity value, the output high, the green light is not lit;
DO output of the microcontroller directly connected through the microcontroller to detect high and low, to detect changes in environmental humidity;
DO output terminal can be directly driven shop relay module, which can form a humidity switch, control equipment to work in a suitable environment;
