BMP085 Analog Barometer & Temperature Sensor

The BMP085 is an analog barometer/atmospheric pressure sensor coupled with a temperature sensor. It’s analog and uses a two-wire I2C interface. I got mine from Adafruit. They include some pin headers you can solder to it or you can wire it up directly.

A great tutorial from Adafruit is here.

It’s a pretty little sensor..

Below is the sketch for it along with the library and some data sheets.

#include <Wire.h>
#include <BMP085.h>

BMP085 bmp;

void setup() {

void loop() {
Serial.print(“Temperature = “);
Serial.println(” *C”);

Serial.print(“Pressure = “);
Serial.println(” Pa”);
