Environment Sensor - Barometer

Introduction
------------
Environment Sensor will using built-in sensor to measure real pressure and calculate altitude data. At the same time, we provide GPS altitude to calibrate.

Function
------------
* Using data table to get sensor's data.
* Double Taps map view into cruising model.

Feature
------------
* Using barometer to forecast weather.
* Using GPS altitude to calibrate station altitude.
* Double Tap map.
* Pressure Camera
* Weather Information

Note:
------------
** Barometer only support iPhone 6, iPhone 6 Plus and newer devices.
*** Station altitude is base on math formula on standard conditions (25 Cº and sea level pressure in 1013.25 hPa) data should inaccuracy match to real altitude.
*** Different device have instrument error while call barometer.
