In most high-g applications, a single (3-axis) acceleration sample at

the peak of an impact event contains sufficient information

In this mode the device returns only the over threshold

help
|

Activity detection can be configured as referenced or absolute.
|
|
When using absolute activity detection, acceleration samples are
|
|
compared directly to a user set threshold to determine whether
|
|
motion is present. In many applications, it is advantageous for
|
|
activity detection to be based not on an absolute threshold,
|
|
but on a deviation from a reference point or orientation.
