Linear interpolation approximates a local set of data into a linear function

Steinhart-hart function is better at approximating thermistor behaviour

Code

Steinhart-hart coeifficient

Coeiff Calculator

Using the sample data from Datasheet for R1, R2, R3 → T1, T2, T3; we can generate a predicted model function

At 100°C the predicted R value is 3.33Ω which corresponds to 3.3051Ω on the datasheet

$A=0.8153122506e^{-3}$

$B=2.240693240e^{-4}$

$C = 0.9025712244e^{-7}$

Temperature is in Kelvins

$\frac{1}{T} = A + Bln(R) + Cln(R)^3$
