Scaling
        Setting                Description                      Units for Threshold
         0x00                    +/- 2g                                 0.016g
         0x01                    +/- 4g                                 0.032g
         0x02                    +/- 8g                                 0.062g
         0x03                    +/- 16g                               0.186g The scaling parameter defines the G-force (1g is the force of gravity) range that the internal accelerometer operates with, and the lower settings will be more sensitive than higher settings. The threshold setting will have units based on the scaling factor as shown in the table above. For example, if the scaling is set to +/- 2g (2x the force of gravity), then the threshold setting can be multiplied by 0.016g to calculate the total G-force threshold. The accelerometer is measured every 250ms and if the difference between two consecutive measurements exceeds the threshold, then a message is sent.
The minimum setting for the acceleration change threshold is 5. If a lower number is programmed, the sensor will not generate an event. Note:
For best practice, use the largest scaling factor that the system will allow and the smallest threshold. For example, use a threshold of 5 with scaling factor 4g instead of threshold of 10 with 2g.
Settling Window In order to prevent continuous reporting of movement events, a “settling window” is used to ensure movement has stopped before the sensor reports a new event. In other words, the settling window defines the amount of time where the acceleration of all axis must stop changing before the sensor will report another event. The settling window time sets has units of 250ms increments (range of 250ms to 63 seconds). The default settling window is 5 seconds.
