Warsaw was caught in smog for several days,
with pollution levels exceeding 800% of the adopted standard.
This was covered by media and followed by even more furious discussion online.
To build a network of low-cost IoT air quality sensors
for public and open-source use.
To develop a website that would publish data collected
from the sensors and show a real-time information
on air pollution in Warsaw.
Following our research on the pollution measurements
already available on the market,
we found out that there were significant variations
among sensors and no protocols
or standardisationin regards to this matter.
Our priority was to keep the low costs
to enable wide network of sensors
to be developed.
We also had to ensure the readings accuracy
to participate in ongoing dialogue on air quality.
Design & develop air quality monitor
able to measure both PM 2,5 and PM 10
by utilizing an optical sensor.
Our sensor includes:
Microcontroller with wifi board
The Plantower PMS3003
Air Quality Sensor (PM1 PM2.5 PM10)
Humidity & temperature sensors API
To get insight of our future customers’ preferences
we conducted over 350 interviews,
surveys and observations.
The entire project was developed in Design Thinking
approach. Why Design Thinking?
It provides an alternative approach to traditional
problem-solving by firstly
identifying the pain point and then building a product
that fulfils a need and solves a problem.
It’s extremely useful in tackling complex problems
that are ill-defined or unknown, by understanding
the human needs involved
and re-framing the problem in human-centric way.
Collected data was presented on interactive map.
Users were able to check pollution level
at their current location.
