I am working on a PLC project that needed to use Thermistors for temperature measurements. This is not a new topic, but for my current application I decided to see if I could do this without the traditional lookup table and linear interpolation algorithms.
My application did not only required accuracy over a range or 30 or 40 degrees C.
I was able to get the math for converting ADC counts to temperature to a single equation for my application:
y# = x * 2.1095E-2 - 3.3485E+1
No lookup tables.
So I am sharing how I got to this sort of solution. Perhaps, it would be useful to others.
I have attached the documentation to this message. I will post the Excel spreadsheet on the next message in this thread.
