The Professional Solution
6
• 76 multi-function stations• huge and extremely expensive• 10+ meters above the ground• well-mixed atmosphere
Dr. Ling-Jyh Chen ([email protected])

But, the question in our mind is just so simple that…
What’s the air quality here and now?

Dr. Ling-Jyh Chen ([email protected])
We start the “participatory sensing" project in 2013
9
low-cost sensors recruiting volunteers
big data and spatio-temporal analysis
MAPS
Dr. Ling-Jyh Chen ([email protected])
Then, we realized that…
11
MAPS
cheap but inaccurate.. friends and students..
The data is small, sparse, and nothing we can analyze
low-cost sensors recruiting volunteers
big data and spatio-temporal analysis
Dr. Ling-Jyh Chen ([email protected])
After MAPS met LASS (2015/9)
12
MAPS
I don’t think we can overcome the scalability issue
Why are we always reinventing the wheels?
I really want to build a “participatory sensing” system
Dr. Ling-Jyh Chen ([email protected])
Then, the journey starts

The journey is speeding up• from 1 to 100 to 1,000 devices
• from 10km to 1km to 100m density
• from Taiwan to Asia, to the world
• involving academia, community, industry, and government

It’s not just a system by someone or some people. It’s an ecosystem by MANY parties of same goals.
Dr. Ling-Jyh Chen ([email protected])
The ecosystem in a nutshell
16
The core spirit: open hardware/software/data
Dr. Ling-Jyh Chen ([email protected])
17
The basis: lots of dirty works and experiments

Well, is this what we want?
31
sophisticated dashboard?
smartphones everywhere?
Dr. Ling-Jyh Chen ([email protected])
Let’s think about it deeper…
32
Can we enable something that never could be possible without LASS/AirBox?
Dr. Ling-Jyh Chen ([email protected])
Example 1: Emission Source Tracking

Dr. Ling-Jyh Chen ([email protected])
Many issues remaining
38
Correlation with traffic and
stationary emission sourceLASS/AirBox
device ranking
Smog forecast
Finer-grained PM2.5
dispersion model
Post-deployment sensor calibration
On-demand response
Government policymaking
Dr. Ling-Jyh Chen ([email protected])
We look forward to collaboration
41
Become the first node in your city
Promote LASS/AirBox in your city
Work together on data analysis
Contribute your crazy ideas and work together on that
Make your city smarter based on this system

Advertisements• ASEAN IVO meeting on 2016/9/5,6
• LJ will give the keynote
• Dr. Lim Hock Beng will give the tutorial
• 15 AirBox (free) for volunteers
• LASS International Deployment Plan
• We plan to expand our deployment to 120+ countries by 2017/7
• Please follow us on Facebook42
Dr. Ling-Jyh Chen ([email protected])
Summary of the talk• We present the AirBox ecosystem for
PM2.5 monitoring.
• The core spirit of the ecosystem is “openness” for HW, SW, data, and mind.
• The journey is ongoing and speeding up; and we look forward to your participation.
• More details (& hands-on) will be given in ASEAN IVO/PRAGMA; and feel free to follow us :)
