I have used I2C over a few metres in quiet locations as a short term fix but my preferred method is use a satellite Micromite 170 with the sensors and run RS422 over cat 5 or 6 cabling. I have runs up to 50-60 metres. The same cable also supplies the power to the sensor module.
I have lost some of the equipment due to lightning strike but seeing that I did loose just about every electronic device in the house with one strike a few years ago, I do expect the occasional loss.
