3. The Desk Occupancy sensor may be mounted on the underside of a desk using the double-sided
tape provided. For best results, mount the sensor horizontally approximately 25 cm from the front
edge of the desk, as shown in Figure 9.
Figure 9: Desk Occupancy Sensor
Note: The sensor will send a message when motion is detected. No additional messages will be sent
as long as motion is detected anytime within succeeding 5 minute windows. Only after detecting no
motion during a 5 minute period will it send a message indicating that the desk is unoccupied.
Therefore, changes in condition may not be reflected in the dashboard immediately.
The daily Desk Occupancy statistics shown on the dashboard are calculated for the preceding day at
midnight.
4. To detect movement in a room, place the Room Occupancy sensor on a flat surface, such as a table
or bookshelf. The Room Occupancy sensor behaves much like the Desk Occupancy sensor. The two
have different parameters configured to account for the size of the space being monitored.
As with Desk Occupancy statistics, Room Occupancy statistics are only calculated for the preceding
24 hour period at midnight each day.
5. To detect the temperature and humidity in the room, place the Temp/Humidity sensor anywhere in
the room. To mitigate momentary changes in temperature due to opening a door or window, best
practice is to place this sensor away from doors and windows.
