Dataq offers a @5$ data aquisition unit that includes hardware and
software.
See:
<http://www.dataq.com/194.htm>
I use a similar unit that they no longer offer to monitor and log
barometric presuure during thunderstorms and Tornado watches and
warnings. I am using a sensor that is similar to aaccelerometer.

For details see:

I have 2 0~6PSI units seperated by 200' and it is interesting to see a
preasure wave, not wind come through.

A big advantage of the Dataq unit is they operate very well on a less
then current PC. I use a P1/MMX 266MHz Toshiba Satellite laptop that
a friend was going to toss because it was "just too slow".
