I'm trying to use a PT100 probe on a Arduino and log it via the serial port, now the logging part is not the problem but the 100 - 130 ohm from 0 - 100 deg. C is.
Is there any of you that have tried PT100 on a Arduino board?
Been looking at the Wheatstone bridge to see if I could sort it out the old and easy way but not sure I get the linearity I hoped for.
You might ask why use PT100 and the simple reason is linearity, and rough environment.
I'll take all ideas with open arms
