Wiring for Radiation Frost Detectors (as of January 2022)
Measurement devices (e.g., datalogger, controller) do not measure resistance directly, but determine resistance
from a half-bridge measurement, where an excitation voltage is input across the thermistor and an output voltage
is measured across the bridge resistor (circuit diagram shown on page 13 is for simulated leaf thermistor).
White: Therm 1 (positive leaf thermistor lead)
Red: Excitation channel (excitation for leaf thermistor)
Black: Therm 1 (negative leaf thermistor lead)
Clear: Shield/Ground
