Monitor air with app
What did I do?
For this project, we developed an app that will connect to a portable air quality sensor. We use those air quality information to help users be better informed and prepared with surrounding environment.
Be informed of surrounding air quality
Learn about air particles
Get advice on what precautions they can take for various air qualities
User goal
Business incentive
Project initiative
Why building a mobile app?
Collecting air quality data across country
A nonprofit organization
Why is knowing air important?
National average AQI
98
In china
Beijing's Average AQI
168
In 2016, Beijing AQI peaked at
700+
AQI below
40
is consider good
AQI above
150
Is considered very unhealthy
AQI above
300
Is considered hazardous
How might we provide accessible and accurate air quality information for people who are sensitive to particles in the air?
Empower hardware with software
Tailor a design fit their role and improve usability
Design solution
With the help of sensor, air quality is more accurate
More accurate air quality
Apple weather app AQI
Accountant dashboard
In new dashboard, users can view all the metrics all at once.
We added more info graphics to help quick understanding on the data.
With the help of sensor, air quality is more accurate

What to do
Accountant dashboard
In new dashboard, users can view all the metrics all at once.
Rich data set
We customized a unique card for each type of air quality data we collected
Crowed sourced heat map
We encourage users to share their sensor data with the community to build an accurate heat map
Switch to pattern design to be more accessible
Color-coded index
Each color response to a range based on U.S. Air Quality Index guideline
How did me measure success
Results and metrics
—from one of the studyparticipants
— from our lead engineer
“This app literally saved my life in an unexpected way”
“I hope in the future, we can widely spread our device and inspect each environment factor in the city”
