/* 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). |
