I spent the last days working on the MS5611-01BA high resolution pressure sensor. I wrote an Arduino library for it which you can find on my bzr repository:
browse repositorydownload libraryuse bzr co http://repository.varesano.net/MS561101BA/ to get a copy directly using bzr.- the MS5611 library is now part of the FreeIMU library. Please refer to the FreeIMU library for newer code.
The library comes associated with a Processing visualization sketch which you can use to visualize a the readings coming from the sensor using a graphical tool.
The results I’ve got so fare are pretty good. Precision is about 0.02-0.03 mbar and altitude estimation resolution is about 10-15 cm. Relative measurement of altitude using the sensor looks very good but I’m still looking for a better approach on absolute altitude estimation.
In the video below you find an example of my initial developments.
