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'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
This breadboard-friendly board breaks out all pins of the BMP085 to a 4-pin 0.1" pitch header. We've also put two 10k pull-up resistors on the I2C lines.
Features:
- Digital two wire (I2C) interface
- Wide barometric pressure range
- Flexible supply voltage range
- Ultra-low power consumption
- Low noise measurement
- Fully calibrated
- Temperature measurement included
- Ultra-flat, small footprint
Dimensions:
- 15.2 x 15.2mm

Use this with original AP 328 , a good value @ $19
It is amazing that load cells can measure a static load strain that is used for a barometric sensor.
The piesio quarts crystals have came a long way with small strain guages even today.
Isn't that the same sensor already on APM???
Would this be more sensitive than the APM's built in barometric pressure sensor? Is something like this even supported by ApM/arducopter right now?
