Presence Detection

lighting applications presence detection

Presence detection optimizes energy usage by ensuring that lights are only on when required. In a fully automatic environment, lights are switched on when the area is occupied and switched off when no occupancy was detected for some time. In a semiautomatic environment, lights can be switched on (and off) manually and are switched off once the area becomes vacant.

Presence Detection

Presence information is typically provided by sensors. LOYTEC provides sensors suited for most application, but also allows seamless integration of sensors by many other vendors, guaranteeing you can choose the sensors which suit your application best. Following LOYTEC’s holistic approach, the presence information collected in the lighting control system is also provided to the other automation systems in the building (e.g. HVAC, access control, etc.). Vice versa, it can also be provided by sensors already present in the building or by other sources in the buildings automation system (e.g. access control).

In office spaces even the PC activity of the occupants can be used to determine the occupancy state of the room: If the L-WEB clients installed on the PCs detect inactivity of the PC user, they reportthis information to the building system. Similar to the PC monitor entering standby, the lights in the room are switched off.
