SparkFun Soil Moisture Sensor for Micro:bit

The SparkFun soil moisture sensor for the micro:bit will allow you to measure the moisture level in soil. The sensor consists of two probes and three pads (PWR, GND, and SIG). The value read on SIG is dependent on a few variables, soil composition, contact on the probes, soil compaction, and other factors. In most cases, it will behoove you to calibrate your sensor reading for each soil sample and sensor. Once calibrated, for a fixed sensor, the primary variables to measuring conductivity in the soil will be the power input and moisture content of the soil.

Quick Spec

  • PWR: INPUT: Power to the sensor (3.3V-5V)
  • SIG: OUTPUT: Analog voltage representing conductivity between probes
  • GND: REFERENCE: Ground reference (0V)
  • Probes: Used to sample soil moisture content for sensor
