Hi, I'm trying to read some resistance values (resistive sensors) with an Arduino Due (3.3V). I'm using a voltage divider to avoid independence of voltage applied, using of course a reference resistor (1% tolerance) carefully measured but values obtained are far of real ones. Example: temperature …

Precision of resistor measurements...

Can you post a diagram of how its wired up, and ideally a photo of the setup too?
