> Hello Herbert:

For a low cost barometric pressure sensor consider the MAP (Manifold
Absolute Pressure) sensor from any late model GM car.
I have not tried it, but you should get a very rugged and temperature
compensated sensor.

See my sensors web page for more ideas (it was done with weather as one
of the targeted applications).
