Barometric Pressure Sensor - BMP085 Breakout Retail

Replacement:RTL-11284. We've made some minor hardware changes this time around. This page is for reference only.

This is a simple breakout board for the BMP085 high-precision, low-power barometric pressure sensor in retail packaging. 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 6-pin 0.1" pitch header. The analog and digital supplies (VDDD and VDDA) of the BMP085 are tied together and broken out to a single pin. We've also put two 4.7k pull-up resistors on the I2C lines.

  • 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* 0.65 x 0.65" (16.5 x 16.5 mm)

  • FYI: I put together a cpp library, please see: http://code.google.com/p/bmp085

    #include "bmp085.h"
    
    bmp085 BMP085;
    
    void setup()
    {
      Serial.begin(9600);
      BMP085.Calibrate(); 
    }
    
    void loop()
    {
        BMP085.refresh();
        Serial.print(BMP085.pressure);
        Serial.print(", ");
        Serial.println(BMP085.temperature);
    
        delay(5000);
    }
    

  • Out of curiosity, how do you choose which products get the clamshell packaging? Do you just pick the most popular products?

    • It depends on which ones we need to put into clamshell packaging for distributors, but generally, yes, it is the most popular products.
