Description
Soli Moisture Detection Humidity Sensor Module AB054
- Soil moisture module is most sensitive to the ambient, generally used to detect the moisture content of the soil.
- When the module can not reach the threshold value, DO port output high, when the the soil humidity exceeds a set threshold value, the module D0 output low
- The small board digital output D0 can be connected directly to the MCU, MCU to detect high and low, to detect soil moisture
- Small board digital output DO can directly drive the buzzer module or relay module in our store, which can form a soil moisture alarm equipment
- Small board analogy output AO and AD module connected through the AD converter, you can get more precise values of soil moisture
