Steinhart-Hart Equation for Thermistor Temperature

ThermistorTemperatureSteinhartHart Estimates the thermistor temperature using the Steinhart-Hart equation

ThermistorTemperatureSteinhartHart(R, R0, A, B, C=0, D)

Arguments

• R: measured resistance for temperature T
• R0: resistance at temperature To (25°C, expressed in ohms)
• A: Steinhart-Hart Coefficient A1 (K^0)
• B: Steinhart-Hart Coefficient B1 (K^-1)
• C: Steinhart-Hart Coefficient C1 (K^-2)
• D: Steinhart-Hart Coefficient D1 (K^-3)

Returns

• R: resistance

Note

Equation ThermistorCalibrationEquation should be used instead of the Steinhart and Hart equation because the performance of this equation is affected by: 1. the thermistor's R(25 C) value 2. the unit of measurement 3. R0 5. the thermistors being connected in series or parallel
