The Steinhart-Hart equation is an empirical relationship between the temperature and resistance of a thermistor with a negative temperature coefficient (that is, a thermistor whose resistance decreases with temperature).

1/T = A + B*ln(R) + C*ln(R)^3

A, B and C are determined by calibrating the equation against experimental data. This application fits data for a A-10K3A1 thermistor to the Steinhart-Hart Equation.

Specifically, this application implements the method of determining A, B and C described on the Wikipedia page for the Steinhart-Hart equation. This approach uses three pairs of values of temperature and resistance.
