This document describes the output from the Arduino DUE, that is parsed and stored.

Directly parsed into the SQLite database
    Event: sub second micros:SubSeconds; Event Count:x
        Meaning: An event has happened at SubSeconds in this second. Event Count is as continuous counter starting at boot.
    TemperatureC: X;
        Meaning: Current average of all temperature sensors, in °C.
    Humidity: X;
        Meaning: Relative humidity in %.
    AccelX: X;
        Meaning: Acceleration in X-direction in m/s^2.
    AccelY: X;
        Meaning: Acceleration in Y-direction in m/s^2.
    AccelZ: X;
        Meaning: Acceleration in Z-direction in m/s^2.
    MagX: X;
        Meaning: Magnetic field in X-direction in Gauss.
    MagY: X;
        Meaning: Magnetic field in X-direction in Gauss.
    MagZ: X;
        Meaning: Magnetic field in X-direction in Gauss.
    Pressure: X;
        Meaning: Pressure in mbar.

Strings starting with '$' are strings coming from the GPS.
From there we extract and store into the SQLite database:
    Longitude
    Latitude
    UTCUnixTime
See the NEMA documentation for more info on these strings: http://aprs.gids.nl/nmea/#gga

Currently unused output:
    TemperatureCHumid: X;
        Meaning: Temperature reported from the humidity sensor in °C.
    TemperatureCBaro: X;
        Meaning: Temperature reported from the pressure sensor in °C.
    Altitude: X;
        Meaning: Altitude reported from the pressure sensor in meter.
