SparkFun gator:soil - micro:bit Accessory Board


Measure Soil Conductivity

The SparkFun gator:soil micro:bit Accessory Board makes it easy to measure soil moisture levels using micro:bit. The two probes on the gator:soil measure soil conductivity that can be used to determine moisture levels. As part of SparkFun's gator:bit series of alligator-clippable accessories, it can be easily interfaced with the micro:bit or other microcontrollers via the SparkFun gator:bit.

  • Bring middle school science to life
  • By measuring soil conductivity, the gator:soil can determine moisture levels of the soil
