Input. Be sure to use a reference resistor with a tight enough tolerance to achieve the accuracy
in temperature you desire.
Measurement Setup
Converting the thermistor resistance to temperature is typically done with the Steinhart-Hart
equation, shown below. T is temperature in Kelvin, R is the thermistor resistance in Ohms, and
A, B, and C are constants corresponding to the thermistor, usually supplied by the vendor.
Alternatively, if the vendor supplies a table of resistance vs. temperature, use a Lookup Table for
processing.
