hi there I'm looking for a temp sensor that I can use with my arduino couple of things I need to bear in mind is the lengths of the cable run could be up to 100m and there is a chance that the sensor could get paled out and the cable being shoed.
I have looked at the DS18B20 I presume I would have to run all 3 cause because of the length? and the volt regulator would not like being shoed?
did look at this: http://uk.mouser.com/ProductDetail/Vishay/NTCLP100E3472H/?qs=%2Fha2pyFaduhmWE0I5%2F0lUWtfX8rOgM2KbyZFmBhB%252bYgmKCZRDfj59w%3D%3D

if you want to 'roll your own' there are some chips that might do what you want. Some can run on parasitic power which means only 2 wires, ground and signal. Not sure about the cable length, though.
I am pretty sure there is a surface mount version of this as well. It uses a '1Wire' library to communicate. There may also be a breakout board available for one of these kinds of sensors [didn't see it in an initial search], or perhaps an I2C device.
