Bosch Sensortec BMP085 pressure sensor tests
The Bosch Sensortec BMP085 is slightly larger (5×5 mm) and has been out for some time. In its highest sensitivity mode it offers 0.01 hPa resolution and 0.03 hPa noise level. (Note: 1 millibar = 1 hPa). What really counts, though, is the accuracy and repeatability. In my comparison of two BMP085 devices, I found they differed by about 0.4 hPa up to 0.6 hPa in the same temperature & pressure environment, so the absolute accuracy of a given device would not be better than that.
