What’s PM2.5?
3

PM2.5 Health
4
1. Par'culate ma.er enters our lung
system through the nose and throat.
2|3. The larger par'culate
(PM10) is eliminated through
coughing sneezing and swallowing.
4. PM2.5 can penetrate deep into the
lungs. It can travel all the way to the
alveoli, causing lung and heart
problems, and delivering harmful
chemicals to the blood system.

PM2.5 Disease (WHO)
5
3 million deaths
attributable to ambient air pollution
4.3 million deaths
attributable to household air pollution

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.

The Professional Solution
7
• 76 multi-function stations (TW)
• huge and extremely expensive
• 10+ meters above the ground
• well-mixed atmosphere

We ask a very simple question…

What’s the air quality
here and now?

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?

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.
27

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

opportunities

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!
