// Calculate altitude assuming 'standard' barometric

// pressure of 1013.25 millibar = 101325 Pascal

// you can get a more precise measurement of altitude

// if you know the current sea level pressure which will

// vary with weather and such. If it is 1015 millibars

// that is equal to 101500 Pascals.

Serial.print("Real altitude = ");
