The YL - 27 soil moisture sensor and the YL - 10 modules are sensitive to the ambient humidity and are generally used to detect the moisture content of the soil. When the module is set to reach a threshold value that has been set with the blue pot. If the D0 port output is high the humidity is high. If the D0 port output is the humidity is low. The digital output D0 can be connected directly with a microcontroller to detect high and low by the microcontroller to detect soil moisture.
