1.The moment a Sensor Node detects occupancy, the luminaire responds by outputting a predetermined light level. It simultaneously communicates with its immediate neighbour luminaires using a Level 1 proximity limited wireless infrared signal, telling them it can see someone.
2.On receipt of this Level 1 signal the neighbouring Sensor Nodes know that there is someone within one light fitting of them, and respond by outputting a predetermined light level appropriate to that occupancy profile (e.g. 80% brightness). They simultaneously relay a Level 2 signal to their own neighbours, notifying them of the occupant’s relative proximity.
3.This propagates throughout the floor, creating the Occupancy Information CloudTM. Each Sensor Node receives signals indicating how close someone is to it, and responds by emitting the appropriate light level based on the rich occupancy information it continually receives (and disseminates). The Occupancy Information CloudTM is illustrated above.
