The 1wire sensors are very well supported on the rPi and very easy to add. 
There is support for 1wire in the kernel and it is readily accessed 
through the /sys tree or python libraries.

The main thing you have to worry about is that the GPIO pins are connected 
directly to the CPU, so you are essentially adding antennas to the CPU 
when you wire such sensors to the GPIO pins.  In a high RF environment 
this can spell disaster.
