Desk Occupancy Dashboard Follow
This article acts as a walkthrough for the EnOcean demo desk cccupancy dashboard. Included is an explanation of the scenario and how to use the provided demo sensors in the context of this dashboard.
Scenario Overview
This scenario is used to show a possible use case for MobiusFlow in the context of Desk Occupancy or any other situation in which monitoring of vibrations or acceleration is required.
In this scenario, the vibrations in one or more of the axes are used to detect if a person is sat at a desk or not. If the detected vibrations go beyond a given threshold, the system will register that a person is sat at a given desk. If there have been no detected vibrations above the detection threshold for 5 seconds, the system assumes the desk is now no longer occupied and updates accordingly.
In a real-world situation, a desk occupancy system would typically use a dedicated EnOcean under desk occupancy sensor. Such a sensor can be purchased from the iaconnects website.
Functionality
On navigating to the Desk Occupancy dashboard the following pane is presented.
Assuming the demo multi-sensor has been left still for at least 5 seconds, the dashboard display should be similar to the above screenshot. It can be seen the minimal vibrations detected by the multi-sensor are not significant enough to detect occupancy and as such, the desk occupancy state shows the desk is not occupied.
Selecting Axes
It is possible to select which axes are used for detection. Switch on or off axes by clicking on the switches UseX, UseY and UseZ below the graph.
Triggering Occupancy
To trigger the occupancy, gently move or shake the multisensor. This should increase the vibrations sufficiently enough to detect occupancy. This is show below
Resetting Occupancy
After 5 seconds of no significant detected vibrations, the system assumes the desk is empty again so the desk occupancy state is reset accordingly.
