Temperature compensation montage ?

hello,

i'm going to make an alcohol sensor, i want to make a temperature compenation systeme using a thermistor. I need help to make the wright montage ?

Thanks

Its still in progress, but here is what I have for thermistor calibration

and some forth code for driver and demo. You don't need to use forth, its very simple, you should be able to get an idea from the code.

Are you sure you want to use a thermistor? A solid state sensor has a linear voltage vs temperature response and is generally simpler to interface to a microcontroller.
