Formulas
for values > 0℃:
R t = R0 ( 1 + 3.9083E-3 t + 5.775E-7 t 2 ) R rsub{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 rsub{t} = R0 * (1 + 3.9083E-3 * t + -5.775E-7 * t^2 + -4.183E-12 * (t - 100) * t^3);

How it works

Rt:resistance of the temperature sensor in Ω
The algorithm calculates the temperature based on the given resistance.
