Temperature versus ADC value

The temperature table below shows temperature versus thermistor ADC value (hex and dec) with gain=1, and ADC mv for the thermistor and ADC on the Mackerel AMW004-E03.x and the Moray AMW006-E02.x. See Peripherals, ADCs. The table assumes the nominal Vref of 3300mV.

The conversion to mV uses the formula

adc_mV = (Vref * adc_value)/adc_max_value

This table is accurate within a few degrees celsius. For full thermistor characteristics search for MuRata part NCP18XH103J03RB.

For a LUT corresponding to this table, see therm_celsius_lut.csv.

Note: Adjust as necessary if Vref is not equal to 3300mV. 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.
