Essential Question

How can we use sensor data to understand, monitor, and improve the air we breathe?

Lessons

Key Concepts

CO2 Monitoring

  • Outdoor: ~420 ppm
  • Good indoor: <800 ppm
  • Moderate: 800-1500 ppm
  • Poor: >1500 ppm

PM2.5 Monitoring

  • Good: 0-12 μg/m³
  • Moderate: 12-35 μg/m³
  • Unhealthy for sensitive: 35-55 μg/m³
  • Unhealthy: >55 μg/m³

Data Analysis Skills

  • Time-series graphing
  • Calculating averages
  • Identifying patterns
  • Comparing conditions

Evidence-Based Decisions

  • Data supports claims
  • Quantify improvements
  • Make recommendations
  • Communicate findings

Materials Needed

Budget option: Many activities can use publicly available data from PurpleAir or AirNow if sensors are unavailable.
