These sensors, which monitor and control lighting, and also detect occupancy and motion, offer substantial energy savings.
In embodiments, at least one of the lighting systems may be an LED lighting system.
Passive infrared sensors rely on a clear line-of-site view that makes 100% coverage cut off possible.
These units have a unique Fresnel lens that divides the coverage into zones, enhancing detection of small movement, without false activations.
Constant innovations in technology are leading the lighting industry and LED luminaires are streamlining the process further.
Occupancy sensors are used to save energy and provide automatic control.
Scheduling is also often appropriate for public spaces where occupancy is typically predictable and based on a schedule — or where the lights must remain on even when the space is unoccupied, such as lobbies.
