It's not a camera

After attempting to use a bmp085 as a temperature sensor for my skiwax 
program ( and not getting good 
results (at least partially due to thermal leakage through the i2c 
wires), I added a mlx90614 to my freerunner.  It is an infrared 
thermometer with a temperature range of -70C to 380C.  It reacts quickly 
to changes in temperature and sort of fits in the freerunner case. 
Installation is similar to the Freerunner Navigation Board install. 
Christoph Mair has written a kernel module for it.  The module is on 
gitorious, but is not yet available upstream.

There is a similar part called a mlx90615 which is much smaller, but 
also has a smaller temperature range.  It may not work with the current 
kernel module, but could probably work with small changes.
