Noise pollution is just the sort of problem that smart city networks, like those
being created in Chicago, Barcelona, and Amsterdam, are designed to help
solve—sensor data gathered at a city-wide scale can help urban planners to
understand how public spaces are being used and to make informed decisions
about how to improve them. We’ve built a simple noise sensor using an
Arduino Yún and an accompanying web app using our Yelp, Amazon, and
Google Geocoding Choreos to do the job.
