Wireless Sensor Network for Smart, Multisectoral Lighting Management

This article describes a mesh wireless sensor network that manages the lighting of large buildings and areas that allow separation of individual sectors within them. If there are no visitors in any of the sectors, the system turns off the lights in them and thus saves electricity. When any visitor appears, the system activates the lighting in the corresponding sectors and in the adjacent ones, thus preserving the comfort of the vision and the visitor is left with the impression that the whole area is fully illuminated. Apart from being a green technology, this approach provides additional benefits, such as easier guarding of open spaces and buildings with windows in the dark hours. The components used are easily available and allow for budget and, at the same time, efficient implementations.
