    I considered a DS1820 but was concerned about the 1-wire network immunity to noise... I want to have at least 5 temperature sensors 3 indoor, two of which will be up to 200 feet from the PIC probably running along side Romex 120v AC lines. An outdoor sensor and a sensor in a thermowell in a boiler ~180 Deg.F. Thermistors are industry standard in a boiler so I didn't want to reinvent the wheel. And as for the longer runs I just figured the thermistor lines could be filtered with some caps since they're DC so noise would be less of a problem. I guess adding a buffer will provide a more robust signal. Thanks... I'll look into it a bit more now that I know what to look for.
