Motion detection

This feature is supported by all Abeeway trackers.

Note

Overview​

The tracker embeds a three axes accelerometer, which detects accelerations and triggers motion events. It is configurable with three parameters:

  • motion_sensitivity: Allow a fine tuning of the acceleration intensity to trigger a motion event.
  • motion_debounce: Minimum duration of a movement to be detected (applicable if motion_sensitivity parameter is set to a value between 1 and 99).
  • motion_duration: Define the delay needed without any motion detection to generate a motion end event.

The accelerometer is always active except in OFF mode.

Motion Duty Cycle Percentage​

The tracker stores the % of time tracker had been moving since the last reset of the tracker or when then counter is reset using Clear motion percentage downlink. Motion Duty Cycle percentage (MDP) is reported in motion end uplinks.

Device orientation​

The acceleration values from the three axes are available within the motion end event messages or by sending a specific downlink (Refer to Request device configuration for more details). This allows the application to determine the tracker orientation. Please refer to AN-005_device_orientation for more details on computing device orientation from accelerometer data.
