Electronic Barometer

I really need help building some weather instruments. I heard that most of them can be inexpensively made with simple capacitors and resistors. The one I am having the most trouble with is the barometer. I would really appriciate any help with this topic. Thanks a lot. I just figured that someone on here has built one and would be able to help me.

Thanks in advance,

Cole
