Only condition is, is that one adheres to the gauge and length of wire for the transmission protocol for the sensor in use (taking into consideration all environmental variables (temp, etc)).

I've run 5 meter cables for DS18B20 temperature sensors without any problem. Up to 30 or so meters should work fine in "powered" mode. DS18 can either have a dedicated +5V/+3.3V wire or run in a "parasitic" mode with power leached from the data wire.
