Sensor
A device that is linked to a location and measures its occupancy as well as environmental values, if applicable.
Sensors can use various measurement techniques, for example:
• Motion - occupancy is detected by motion.
• Heat - occupancy is detected based on body heat.
• Video - occupancy is detected by video interpretation.
 | More advanced sensors can support a combination of these methods/ and/or other methods (laser techniques, etc.). |
