BMP085 Breakout Board

High-precision, low-power barometric pressure sensor with I2C connection.

More details



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.
