3. Backgrounds 1/3
● People lives and works inside building up to 90% of time.
● EPA warns seriousness of indoor air pollution.
● In the WHO European Region alone, exposure to particulate
matter (PM) decreases the life expectancy of every person by an
average of almost 1 year(1)
● cause of various illness: asthma, atopic dermatitis, allergy, etc.
○ The prevalence rate of child asthma(2)
■ 13.0%(‘95) - 15.8%(‘00) - 18.6%(‘05)
○ Positive correlation between indoor PM2.5 exposure and the presence of
bronchitis and asthmatic symptoms, especially during the winter season(3)

(7), (8) WHO, Health effects of particulate matter, 2012
The health effects of PM10 and PM2.5 are well documented.
There is no evidence of a safe level of exposure or a threshold below which
no adverse health effects occur(8).
(6)
PM is a widespread air pollutant,
consisting of a mixture of solid
and liquid particles suspended
in the air(7).

● Existiong Sensor or Monitor Device
○ monitors Indoor dust precisely but very expensive.
○ needs professional knowledge.
○ just shows number or index of IAQ
○ doesn’t provide relevant notification in real-time.

9. A system which
- monitors the indoor dust( > 1um) in real-time
- preserve data of PM(Particulate Matter)
- shows the data with GUI using Web Interface
- provides various notification of indoor air quality and
user’s custom monitoring options

- Finding approximate methods of measurement
- Test various indoor air pollution environment.
- Statistical Analysis for finding proper level of indoor dust.

12. Evaluation & Challenge
Evaluation: Nothing new but more functionality
- cheap & GUI Interface with web
- real-time monitoring & monitoring options
- various notification (twitter, mail, …)
Challenge
- how to calibrate the monitored value
- how to validate accuracy of monitored value
We want to focus to find profer level of PM in indoor area.
We want to check PM data ouf our daily life in real-time.
