Why This Is Happening
6
• “Because they can” (low cost, easy to create)
• STEM education• Personal health info and protection• Advocacy for changing policy• Decision making• Research

Maker Faire7
Sponsors: STI HabitatMap Manhattan College NY Hall of Science
Type: EducationApproach:
• Developed AirCasting pods• Let people measure particles• Crowdsourced the data• Interviewed participants
Examples

Air Quality Egg9
Sponsor: Public via KickStarterType: DIYApproach:
• Sought crowdsourced funding ($140k)• Developed 1200+ eggs to measure CO and
NO2• Costs about $150• Results discouraging; didn’t focus on quality
Examples

Mobile Particle Monitoring
10
Sponsor: Tim Type: EducationApproach:
• Use $5,000 PM instrument and $100 PM sensor
• Use AirCasting platform to store and log data
Examples

Kids Making Sense
13
Sponsor: Knight News FoundationType: EducationObjective:
• Prototype concept of Kids Making Sense Approach:
• Develop 5 PM sensors• Develop curriculum for 4-hr class• Teach high school students in Brooklyn and San
Francisco• Evaluate sensor, curriculum, and concept • Report to Knight News Foundation in June
Examples

Potential Concerns with Low-Cost Monitoring
14
• Inaccurate data used by organizations• Confused citizens• Distrust of government• Time drain on AQ agency staff• Unknown process for how data will be
used

Potential Opportunities from Low-Cost Monitoring
15
• Engage new people/advocates for clean air
• Supplement monitoring networks• Lower cost of monitoring• Outreach and education• Peer regulation (local understanding
local solutions)

Future – How Government Can Help
16
• Quality studies• EPA/ORD – sensor evaluations• EPA Air Sensor Guidebook• AirNow Sensor Evaluation Service
• Pilot studies• Demonstrating claims• Establishing value• Community group monitoring• Engaging stakeholders
• Aggregation for ingesting and quality-controlling data
• Health messaging determination
