CHAPTER 3: DEFINITION OF PHYSICAL SENSORS, VIRTUAL
SENSORS, AND ACTIONS
DETAILED EXAMPLE 2:
GDPR-compliant air quality and people count sensors are placed at the entrance of a meeting room. The sensor reports
when one person enters and when one person exits the room. A virtual sensor can be used with AlertWerks™ IoT Web
data to report the number of people in the room. An overnight action can be used to reset the counter to zero. With
another action, you can start ventilation in the room if the air quality or person count in the room exceeds the set
parameters. With another action you can enable a traffic light showing red so that people know to not enter that room.
With Black Box conference and meeting room solutions, you may also move the next meeting to another room by
SNMPSET.
NOTE: For the Black Box air quality and people count sensor (SKU: EM-P), everything is prepared and the datapoint
only shows the number of people in that room.
