Retired RETIRED

This product has been retired from our catalog and is no longer for sale.

This page is made available for those looking for datasheets and the simply curious. Please refer to the description to see if a replacement part is available.

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

Description: 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.

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:

  • 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.
