1.Detecting soil moisture: The soil moisture module is most sensitive to environmental humidity and is generally used to detect soil moisture.
2.When the soil moisture reaches the set threshold, the DO port outputs a high level. When the soil moisture exceeds the set threshold, the module D0 outputs a low level.
3.Principle: The small-plate digital output D0 can be directly connected to the single-chip microcomputer, and the high-low level is detected by the single-chip microcomputer, thereby detecting the soil moisture;
4.soil humidity alarm device: The small board digital output DO can directly drive the relay module, buzzer module, etc., which can form a soil humidity alarm device.
5.Accurate Value: The small-plate analog output AO can be connected to the AD module. Through AD conversion, a more accurate value of soil moisture can be obtained.
