Smart Street Lights
San Francisco plans to reduce its street lighting bill in half by connecting streetlights to mini power grids that can be monitored and controlled remotely; and by installing LED light bulbs. The city would be able to dim street lights where they are not needed, or brighten street lights in response to fog or critical traffic conditions automatically and in real time. This project is a part of a larger pilot program to connect core city services to a unified wireless system in order to deliver services more efficiently.
“Here’s how the pilot project will work. Nodes attached to each streetlight will monitor the light’s power consumption and relay that information to the utility. Using that data, the city can monitor conditions, remotely control the streetlights or set timers or automatic indicators for turning the streetlights on or off.”
