The document describes the Smart Citizen Kit project by Waag, an institute that explores emergent technologies and opens them for societal use. The project involves distributing sensor kits to citizens of Amsterdam to collect environmental data and engage residents in understanding and influencing the workings of their city. An initial pilot with 100 kits provided insights that will inform expanding the project to 500 kits and citizens, with the goal of creating a testbed for businesses and developing new data analysis and visualization tools.
