That reminds me of something I've been meaning to ask. What kind of
sensor would one use to measure barometric pressure electronically?
I've seen "pressure sensors" that only measure a few PSI, but never
something that is optimized for collecting weather data. Surely there
is such a thing?

And on a similar topic, I'm interested in the Philips H1 humidity
sensor, but I can't find a source (even a price) for it. Part of
the problem is the name "H1" is too short for some of the search
engines (e.g. findchips.com). Thanks in advance for any help!
