Motivation
• Mobile phone usage – communication tool > networked mobile personal
measurement instrument
• Real-time environmental data
• Mobile phone can sense and tell us what?
Look around you right now
Were pesticides used on these fruits?
Is the noise level safe here?
Is this water safe to drink?
How healthy is the air I'm breathing ?
How hot is it?
Motivation
• Temperature, humidity, AQI (averaging)
• Real-time pollen counts
• Own actual decibel measurements
Introduction
• Facts about our future mobile phones:– more sensing and processing capabilities – contribute and collective
• data collector
Study 1: Perceptions Of Air Quality
• People's perceptions of air quality• 12 residents (9M/3F 23-56 years old) • Several insights
• None of the participants had a clear understanding
• don't trust the government •
Study 1: Perceptions Of Air Quality
• Ergo: Air Quality On-the-Go
Air Quality Index Bakersfield, CACurrently @3:00 PM = 47 (GOOD) Ozone6/4: 95 (MODERATE) Ozone6/5: 124 (UNHEALTHY FOR SENSITIVE PEOPLE) Ozone
Study 2: Air Quality Sensing Field Study • 7 taxi drivers and 3 students in Accra
For Taxi For student
GPS logger
carbon monoxide sensor
Study 2: Air Quality Sensing Field Study
Research Prototype Platforms
• TI MSP430 microcontroller
• carbon monoxide (CO), nitrogen oxide (NOx), and ozone (O3) gas sensors as well as temperature, relative humidity, and motion (3D accelerometer) sensors
Research Prototype Platforms GOIN' MOBILE: THE STREET SWEEPER
DEPLOYMENT' GOIN '
Street Sweeper gas sensor board, a fan
main board and a mobile phone

When the AQIis in this range:
...air quality conditions are:
...as symbolizedby this color:
0 to 50 Good Green
51 to 100 Moderate Yellow
101 to 150 Unhealthy forSensitive Groups
