WORKED MODELWORKED SOURCECalibrate 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.
- Threshold lies between dry and medium calibration.
- Sensors map a physical state to voltage.
- Calibration range matters.
What behavior should occur at 1.2 V?
