Fall detection using your phone and Arduino Cloud

5  Arduino IoT Cloud Variables description
6
7  The following variables are automatically generated and updated when changes are made to the Thing
8
9  String message;
10  float accel;
11  float fall_intensity;
12  float threshold;
13  CloudLocation fall_location;
14  CloudLocation gps;
15  bool fall;
16  bool fall_clear;
17  CloudTime fall_detection_time;
18
19  Variables which are marked as READ/WRITE in the Cloud Thing will also have functions
20  which are called when their values are changed from the Dashboard.
21  These functions are generated with the Thing and added at the end of this sketch.
