Calibrate a moisture sensor

Sensor voltage versus soil moisture: dry 0.8 V, medium 2.2 V, saturated 3.7 V. A controller waters below 1.5 V.

  1. Threshold lies between dry and medium calibration.
  2. Sensors map a physical state to voltage.
  3. Calibration range matters.

What behavior should occur at 1.2 V?
