1. I'm using an analog to digital converter to read the voltage across a thermistor used to measure engine water temperature. (see attached)
2. The thermistor temperature vs resistance curve is non-linear. (see attached)
3. I was thinking about using LOOKDOWN / LOOKUP but the steps would be in 10 degree increments.
4. I was also thinking about using linear interpolation but maybe there is a better way.
Can anyone suggest a good way of getting a one degree resolution?
