Occupancy Sensors detect occupancy in an area and switches on the lights, when there is no occupancy in the area the lights are automatically switch off.
This sensor technology utilises the fact that the human body radiates heat. Just as light, this heat is part of the spectrum of electromagnetic waves and is known as infrared radiation.
Three highly sensitive pyro sensors detect human infrared radiation; the light sensor measures ambient brightness. Microphonics and High Frequency technology is used where necessary.
In terms of modern building management, this lighting solution affords contemporary convenience and cost-cutting efficiency. The system is practical and simple to operate, and because it only switches on the light when it is actually needed. Occupancy Sensors could reduce your lighting portion of your energy bills by 40% – 90%.
