Formulas

for values > 0℃:

R_{t} = R0 * (1 + 3.9083E-3 * t + - 5.775E-7 * t^{2})

for values < 0℃:

R_{t} = R0 * (1 + 3.9083E-3 * t + - 5.775E-7 * t^{2} + - 4.183E-12 * (t - 100) * t^{3});

R_t:	resistance of the temperature sensor in Ω

The algorithm calculates the temperature based on the given resistance.
