It’s all about the AIR
• You can live without food for 3 months; without water for 3 days; but without AIR no more than 3 minutes.
• You can choose the source of food and water; but have no choices about the air to breath.

From AirBox to Smart City• Smart City does not mean
• we collect a lot of data, or
• we know everything on smartphones.
• AirBox is a smart city infrastructure; but, to be a smart city enabler, it has to go beyond an IoT system
• Can we enable something that could not be possible without 1,000+ sensor nodes?
• Can we make the city smarter?23

These are NOT just for fun
• We have informed the government about our analysis results.
• The national EPA and several city governments have subscribed the data stream of our analysis results.
• We don’t know what on-demand reactions will be implemented, but we are looking forward to that.

Many issues remaining
• Correlation with traffic and stationary emission source
• Finer-grained PM2.5 dispersion model
• Backend calibration model
• Urban microclimates
• On-demand response & government policymaking

Take home messages
• AirBox is a participatory ecosystem for PM2.5 monitoring.
• AirBox is on its way from “IoT system” to “Smart City enabler”.
• Suggestion: Make your system a “must-have” rather than a “nice-to-have”.
• There are plenty of challenges opportunities, and we look forward to collaborating with you!
