Sensitive Baro sensor?

[Eric]

Hey Guys- I'm looking to do an uber-sensitive barometric pressure monitor. Basically I need it to monitor chimney pressure (so a very small pressure difference from atmosphere). Has anyone seen a sensor which is more suited to only a small difference from reference/atmosphere?

An odd project I know

Thanks

No experience with this product, but if I were attempting a similar project I would definitely consider this as it could easily be interfaced with Arduino and has lots of good supporting documentation and code. https://www.sparkfun.com/products/11824

Never used this before, but it appears to have good documentation and claims at least to be accurate. https://www.sparkfun.com/products/11824

Thanks Wes!

At a glance- I think that's exactly what I need. It looks like the measurement should indeed be fine enough for the project. I better go digging around in the bin because I think I may have actually ordered that exact model from a different supplier once upon a time. Time to follow up. Cheers!
