YL69 Soil Hygrometer Humidity & Moisture Sensor for Arduino

• The soil moisture module is most sensitive to ambient humidity and is generally used to detect the moisture content of the soil.
• Module to reach the threshold value is set in the soil moisture, DO port output high, when the soil humidity exceeds a set threshold value, the module D0 output is low.
• The digital output D0 can be connected directly with the microcontroller to detect high and low microcontroller to detect soil moisture.
• The digital outputs DO shop relay module can directly drive the buzzer module, which can form soil moisture alarm equipment.
• Analog output AO and AD module connected through the AD converter, you can get more precise values of soil moisture.
