Converting resistance to temperature
The outputs a resistance value for sensors that contain a thermistor. Temperature is calculated by applying the resistance to a known equation, such as the Steinhart-Hart equation, which converts resistance to temperature.
The Steinhart-Hart equation for converting resistance to degrees Celsius is as follows:
Temperature = 1/(A + B × LN(resistance) + C × (LN(resistance))^3) – 273.15
where A, B, and C are coefficients for the Steinhart-Hart equation.
The coefficients for the Steinhart-Hart equation are specific to the thermistor contained in your sensor and are obtained from the sensor manufacturer.
NOTE:
Please check with the manufacturer to get the coefficients for your specific thermistor.
