Description: The BMP180 is a high-precision, ultra-low power digital barometer. It offers a measuring range of 300 to 1100 hPa with an absolute accuracy of down to 0.02 hPa. The BMP185 is based on piezo-resistive technology for EMC robustness, high accuracy and linearity as well as long term stability. What makes this sensor great is that it is nearly identical to its former rev, the BMP085!
This sensor supports a voltage supply between 1.8 and 3.6VDC. It is designed to be connected directly to a micro-controller via the I²C bus
The BMP180 comes in an ultra-thin, 8-pin ceramic lead-less chip carrier (LCC) package.

I found the BMP-180 very easy to interface to my new digital weather station which uses an ARM-7 microcontroller. Developing the firmware driver for the BMP-180 was very straight forward. The really big surprise was the absolute accuracy of the BMP180. My BMP180 produces readings which are almost identical to the USWS reported values!! It is a great buy. (I spent $45.00 on a Honeywell pressure sensor that not work nearly as well as the BMP180.)
