The SparkFun Qwiic Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials. The soil moisture sensor is pretty straightforward to use. The two large, exposed pads function as probes for the sensor, together acting as a variable resistor. The more water that is in the soil means the better the conductivity between the pads will be, resulting in a lower resistance and a higher SIG out. This version of the Soil Moisture Sensor includes a Qwiic connector, making it even easier to use this sensor!

To get the SparkFun Soil Moisture Sensor functioning, all you will need is to connect the Qwiic / STEMMA QT connector to a compatible Qwiic or STEMMA QT compatible microcontroller or single board computer. Examples on how to read the sensor can be found in the Hookup Guide linked below.



  • Easy to use
  • Qwiic and STEMMA QT Compatible
