Barometric Pressure Sensor - BMP085

The BMP085 is a high-precision, ultra-low power barometric pressure sensor. It offers a measuring range of 300 to 1100 hPa with an absolute accuracy of down to 0.03 hPa. The BMP085 is based on piezo-resistive technology for EMC robustness, high accuracy and linearity as well as long term stability. 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 BMP085 comes in an ultra-thin, 8-pin ceramic lead-less chip carrier (LCC) package.
