This is a simple breakout board from SparkFun for the BMP085 high-precision, low-power barometric pressure sensor. The BMP085 offers a measuring range of 30 to 110 kPa with an absolute accuracy of down to 0.1 kPa. It uses piezo-resistive technology for robustness, 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 microcontroller via an I²C bus.
