Here is an idea that will cost about $150 and do a lot more than measure the
amps.

A Hobo 12-012 data logger with internal temp and RH sensors and 2 external
sensors.

I'm not real happy with this URL. When I accessed it, I got the
following in my Java Console window:

No warning or request. This is bad behaviour IMO. Can't do any harm to
this computer, but even so, I don't like it.

Why is an applet talking home to mommy?

Just why do they need to d/l an applet and run it to provide what on
the face of it is a pretty simple Web page?

I was interested because we make extensive use of dataloggers. The ones
we use are dataTakers - http://www.datataker.com/. These are NOT cheap,
but we run them in Antarctica and on icebreakers for months at a
stretch unattended. I'd like to find something cheaper, but my
electronics engineers express a total lack of faith in USB devices when
run time extends to months straight. Too many bad experiences.
