This is an easy to use digital
soil moisture sensor. Just insert the sensor in the soil and it can can
measure moisture or water level content in it. It gives a digital output
of 5V when moisture level is high and 0V when the moisture level is low
in the soil.
sensor includes a potentiometer to set the desired moisture threshold.
When the sensor measures more moisture than the set threshold, the
digital output goes high and an LED indicates the output. When the
moisture in the soil is less thatn the set threshold, the output remains
low. The digital output can be connected to a micro controller to sense
the moisture level. The sensor also outputs an analog output which can
be connected to the ADC of a micro controller to get the exact moisture
level in the soild.
This sensor is great for making water gardening projects, water sensing, etc.
- Operating voltage: 3.3V~5V

- VCC: 3.3V-5V
- GND: GND
- DO: digital output interface(0 and 1)
- AO: analog output interface
- VCC connect to 3.3V-5V
- GND connect to GND
- DO digital value output connector（0 or 1）
- AO analog value output connector
- Soil moisture module is most sensitive to the ambient, generally used to detect the moisture content of the soil.
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
- The small board digital output D0 can be connected directly to the MCU, MCU to detect high and low, to detect soil moisture;
board digital output DO can directly drive the buzzer module or relay
module in our store, which can form a soil moisture alarm equipment;
board analog output AO and AD module connected through the AD
converter, you can get more precise values of soil moisture;
