What are we going to cover in this talk?

1. Why is PM2.5 important?

2. How did we build the system?

3. What is the current status?

4. What is the next step?

Fine Particulate Matter (PM2.5)

The Professional Solution

6

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


7

But, the question in our mind is just so simple that…

What’s the air quality here and now?

8







We started the “participatory sensing" project in 2013

9

low-cost sensors recruiting volunteers

big data and spatio-temporal analysis

MAPS

2013

2015

MAPS


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


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


What is LASS?

13


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

15

It’s not just a system by someone or some people. It’s an ecosystem by MANY parties of same goals.


The ecosystem in a nutshell

16

The core spirit: open hardware/software/data


17

The basis: lots of dirty works and experiments

The pattern: from academia to community to industry

academia: focus on core issues

community: rapid POC

industry: reliable production

Brief Statistics• Daily active devices

• 500 AirBox, 50 LASS, 20 others

• Taiwan and 15 countries, including Canada, France, Germany, India, Indonesia, Japan, Korea, Malaysia, Netherlands, Philippines, Poland, Singapore, Saudi Arabia, United Arab Emirates, and USA

• Data Service

• about 2 hits/second and 3 GB/day

28


Well, is this what we want?

29

sophisticated dashboard?

smartphones everywhere?


Nice-to-have or Must-have?

30

The Eisenhower Matrix

Urgent Not urgent

Important MUST SHOULD

Not important COULD WOULD(Nice-to-Have)


Let’s think about it deeper…

31

Can we enable something that never could be possible without LASS/AirBox?


Example 1: Emission Source Tracking

32

Something happened on 2015/12/20(UTC time)


Example 2: Periodic Emission Source

33


34

Example 3: Anomaly Detection


35

Example 4: Environment Education

36







Next step: device-wise

• More compact and energy-saving

• Support LoRa and other air quality sensors

37

MAPS 5.0 LASS4U AirBox X.0


Next step: data-wise

38

• Support international standards

• e.g., OGC SensorThings API, FIWARE


Next step: system-wise

• From single-server to distributed architecture

39


Many issues remaining

40

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


Plenty of Opportunities

41


AirBox is an Open Ecosystem

42

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• AirBox/LASS tutorial on 9am tomorrow

• given by Dr. Lim Hock Beng

• 13 AirBox (free) for volunteers

• LASS International Deployment Plan

• We plan to expand our deployment to 120+ countries by 2017/7

• Please follow us on Facebook

43


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.
