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.
