#include <Wire.h> // required by BMP085 library

#include <BMP085_t.h> // import BMP085 template library

BMP085<0> PSensor; // instantiate sensor, 0 = low precision pressure reading

void setup()

{

Serial.begin(9600); // initialize serial, used to display readings in Serial Monitor

Wire.begin(); // initialize I2C that connects to sensor

PSensor.begin(); // initalize pressure sensor

}

void loop()

{

PSensor.refresh(); // read current sensor data

PSensor.calculate(); // run calculations for temperature and pressure

Serial.print("Temperature: ");

Serial.print(PSensor.temperature/10); // display temperature in Celsius

Serial.print(".");

Serial.print(PSensor.temperature%10); // display temperature in Celsius

Serial.write(176); // caractère °

Serial.println("C");

Serial.print("Pressure: ");

Serial.print((PSensor.pressure+50)/100); // display pressure in hPa

Serial.println("hPa");

delay(5000); // wait a while before next loop

}
