Temperature versus ADC value

The temperature table below shows temperature versus ADC value for the Wahoo AMS001-E01.2 thermistor and ADC. See Peripherals, ADCs. This table is accurate within a few degrees celsius. For full thermistor characteristics search for MuRata part NCP18XH103J03RB.

Note: different thermistors may have a different correspondence between voltage and temperature. To create an accurate table for your particular thermistor you can calibrate with an accurate thermometer.
