/* This driver uses the Adafruit unified sensor library (Adafruit_Sensor),
7
   which provides a common 'type' for sensor data and some helper functions.
8
   
9
   To use this driver you will also need to download the Adafruit_Sensor
10
   library and include it in your libraries folder.
11
12
   You should also assign a unique ID to this sensor for use with
13
   the Adafruit Sensor API so that you can identify this particular
14
   sensor in any data logs, etc.  To assign a unique ID, simply
15
   provide an appropriate value in the constructor below (12345
16
   is used by default in this example).
