4 2011-07-08 SparkFun <p> <span style="font-weight: bold;">Description: </span>This is a simple breakout board for the BMP085 high-precision, low-power barometric pressure sensor. The BMP085 offers a measuring range of 300 to 1100 hPa with an absolute accuracy of down to 0.03 hPa. It&#39;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 I&sup2;C bus</p> <p> This breadboard-friendly board breaks out all pins of the BMP085 to a 6-pin 0.1&quot; pitch header. The analog and digital supplies (VDDD and VDDA) of the BMP085 are tied together and broken out to a single pin. We&#39;ve also put two 4.7k pull-up resistors on the I<sup>2</sup>C lines.<br /> <br /> <span style="font-weight: bold;">Features:</span></p> <ul> <li> Digital two wire (I<sup>2</sup>C) interface</li> <li> Wide barometric pressure range</li> <li> Flexible supply voltage range</li> <li> Ultra-low power consumption</li> <li> Low noise measurement</li> <li> Fully calibrated</li> <li> Temperature measurement included</li> <li> Ultra-flat, small footprint</li> </ul> <p> <span style="font-weight: bold;">Dimensions:</span></p> <ul> <li> 0.65 x 0.65&quot; (16.5 x 16.5 mm)</li> </ul> <p> <span style="font-weight: bold;">Documents:</span></p> <ul> <li> <a href="http://www.sparkfun.com/datasheets/Sensors/Pressure/BMP085 Breakout-v12.pdf" target="_blank">Schematic</a></li> <li> <a classname="" href="http://www.sparkfun.com/datasheets/Components/General/BST-BMP085-DS000-05.pdf" name="" target="_blank">Datasheet</a></li> <li> <a href="http://dlnmh9ip6v2uc.cloudfront.net/datasheets/Sensors/Weather/BMP085 Breakout-v13.zip">Eagle Files</a></li> <li> <a href="http://www.sparkfun.com/tutorials/253">Quickstart Guide</a></li> <li> <a href="http://www.sparkfun.com/tutorial/Barometric/BMP085_Example_Code.pde" target="_blank">Example Arduino Sketch</a></li> <li> <a href="http://www.sparkfun.com/datasheets/Sensors/Pressure/BMP085 Example Code.zip" target="_blank">Example Code</a> (ATmega328)</li> <li> <a classname="" href="http://www.sparkfun.com/datasheets/Components/General/BMP085_Flyer_Rev.0.2_March2008.pdf" name="" target="_blank">Product Flyer</a></li> <li> <a classname="" href="http://www.opencircuits.com/SFE_Footprint_Library_Eagle" name="" target="_blank">SFE Eagle Library</a> has this part!</li> <li> <a href="http://wiring.org.co/learning/libraries/bmp085.html" target="_blank">Wiring Example</a></li> <li> <a href="http://mbed.org/users/tkreyche/notebook/bmp085-pressure-sensor/" target="_blank">mbed User Review</a></li> </ul> Barometric Pressure Sensor - BMP085 Breakout http://www.sparkfun.com/products/9694 Barometric Pressure BMP085 Pressure Sensor Breakout VCC
