A thermistor is a type of resistor whose resistance is dependent on temperature, more so than in standard resistors.

The Steinhart–Hart equation is a model of the resistance of a semiconductor at different temperatures.
The equation is
where:
- T is the temperature (in kelvins)
- R is the resistance at T (in ohms)
- A , B and C are the Steinhart–Hart coefficients, which vary depending on the type and model of thermistor and the temperature range of interest. (The most general form of the applied equation contains a (ln R)² term, but this is frequently neglected because it is typically much smaller than the other coefficients, and is therefore not shown above.)
