使用BMP085氣壓傳感器
對比差異
Temperature = 27.60 *C
Pressure = 94461 Pa
Altitude = 587.82 meters
Pressure at sealevel (calculated) = 94456 Pa
Real altitude = 16116.56 meters
Temperature = 27.60 *C
Pressure = 94460 Pa
Altitude = 588.09 meters
Pressure at sealevel (calculated) = 94463 Pa
Real altitude = 16116.62 meters
