Temperature warning USB devices

[Jerry Feldman]

This weekend the AC failed in our computer room which is shared by a=20
number of different companies. I was wondering if anyone had experience=20
with USB temperature warning devices.  Hopefully, Regus, who runs the=20
facility) will install a couple of these, but I might want to install=20
one or more in our servers. Most of these appear to be Windows devices,=20
and all of our servers are Linux.
