Description: This is the retail version of our BMP180 Breakout Board. This is the same as our regular barometer, but in retail packaging.

This is a breakout board for the Bosch BMP180 high-precision, low-power digital barometer. The BMP180 offers a pressure measuring range of 300 to 1100 hPa with an accuracy down to 0.02 hPa in advanced resolution mode. 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. What makes this sensor great is that it is nearly identical to its former rev, the BMP085!

This breadboard-friendly board breaks out every pin to a 5-pin 0.1" pitch header. VCC can be from 1.8V to 3.6V and is 5V tolerant; 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).


  • 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

Customer Comments

  • I love SF but sometimes the pricing baffles me. The BMP180 sensor is $4.95, breakout board with sensor is $9.95 which isn’t too crazy, but toss in a disposable plastic shell and the price goes up to $21..?
