This is a simple breakout board for the BMP085 high-precision, low-power barometric pressure sensor in retail packaging. The BMP085 offers a measuring range of 300 to 1100 hPa with an absolute accuracy of down to 0.03 hPa. It's 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 Project description, more information and ordering can be found at https://www.sparkfun.com/products/9889 Datasheet: http://dlnmh9ip6v2uc.cloudfront.net/datasheets/Sensors/Pressure/BST-BMP085-DS000-06.pdf Quickstart Guide: http://www.sparkfun.com/tutorials/253 Example Arduino Sketch: http://www.sparkfun.com/tutorial/Barometric/BMP085_Example_Code.pde Example Code: http://www.sparkfun.com/datasheets/Sensors/Pressure/BMP085%20Example%20Code.zip Product Flyer: http://www.sparkfun.com/datasheets/Components/General/BMP085_Flyer_Rev.0.2_March2008.pdf Wiring Example: http://wiring.org.co/learning/libraries/bmp085.html mbed User Review: http://mbed.org/users/tkreyche/notebook/bmp085-pressure-sensor/
