Hi
I have a NTC thermistor.
I want to connect to a PIC (PIC18F4520) A/D for temperature measurements.
Is a simple voltage divider circuit good enough?
The curve is non linear for the thermistor. Is there anyway of overcoming this in hardware? Or Software.
Finally if i use a PTC thermistor are there any circuit changes to be made?
Thanks in advance.
