Sensor networks are getting a lot of play in the technosphere these days, and for good reason. Sensors can collect data about human activity—the flow of foot traffic, usage patterns, preferences; the environment—daylight levels, temperature, humidity, the presence of chemicals or other dangers; and things—the locations of items in a warehouse, traffic patterns.
Connected lighting systems are uniquely positioned to serve as platforms for sensor networks. Lighting is already installed everywhere that people go, indoors and—at least in urban and residential environments—outdoors as well. Power is already available everywhere that lighting is installed. And connected luminaires already have the ability to send data “upstream” to IT networks. By integrating sensors into the lighting system, you have a readymade, distributed grid.
