Barometric Pressure Sensor - BMP085 Breakout

Description: BMP085 Breakout is a simple breakout board for the Bosch BMP085 high-precision, low-power barometric pressure sensor. The BMP085 offers a measuring range of 300 to 1100 hPa with an accuracy down to 0.03 hPa in ultra-high resolution mode (that's 0.25m of altitude at sea level!) It's based on piezo-resistive technology for high accuracy, ruggedness and long term stability. These come factory-calibrated, with the calibration coefficients already stored in ROM. Writing your own code for it requires some math, but there are plenty of examples and libraries available (see below).

This breadboard-friendly board breaks out every pin to a 6-pin 0.1" pitch header. VCC can be from 1.8V to 3.6V; we typically run it on a clean, regulated 3.3V supply. The analog and digital supplies (VDDD and VDDA) are tied to a single header pin, but are separately decoupled. It connects to a microcontroller via I²C bus (also known as TWI, or on the Arduino, the "Wire" library).

 

Features:

  • Digital two wire (I²C, TWI, "Wire") interface
  • Wide barometric pressure range
  • Flexible supply voltage range (1.8V to 3.6V)
  • Ultra-low power consumption
  • Low noise measurements
  • Factory-calibrated
  • Includes temperature sensor
  • Low-profile with a small footprint
