ADC question

[Ioannis]

If you want accuracy, why not dump all the hardware and use the DS18B20? It has +/-0.5°C accuracy from –10°C to +85°C. And is purely digital interface. I think Bruce from www.rentron.com has examples for the chip.

Ioannis,
The problem here is not with getting accuracy with using one sensor, the problem here is using multiple sensors and obtaining accurate data. but I think I will looking into the parallax that mackrackit suggested. I will post later with questions and comments. Thanks

So, you can use multiple 1-wire sensors scattered all over the place and connected through one-wire only (and ground of course).

I cannot see the problem.

You will get rid off the op-amps, ADC's etc and WILL have the 0.5 accuracy.
