R1 (Ω)

T1 (°C)

R2 (Ω)

T2 (°C)

R3 (Ω) - Required for Steinhart-Hart mode

T3 (°C) - Required for Steinhart-Hart mode

T = 1/(ln(Rt/R25)/B + 1/298.15) - 273.15

R(25°C)-

B-Value (T1/T2)- K

T = 1/(A×10⁻³ + B×10⁻⁴×lnR + C×10⁻⁸×(lnR)³) - 273.15

Note: B-Value model only requires two sets of (R,T) data; Steinhart-Hart model requires three sets for higher accuracy.
