Adding low-cost sensor data to the platform

Advancements in sensor technology and the subsequent emergence of lower cost sensors have lowered the barrier for entry, encouraging a greater number of participants to produce air quality knowledge. Lower-cost sensors have started to democratize air quality knowledge, enabling everyone from community groups to local governments to citizen scientists to contribute. We want the platform to reflect the diversity of the global air quality landscape, while filling in data gaps and opening up possibilities for better understanding, data-driven action and outcomes.

Given our focus to date on largely reference-grade government data, OpenAQ has been exploring the opportunity to ingest low-cost sensor data for more than a year, incorporating stakeholder feedback from our community along the way. As we previously shared, this led to a close partnership with and funding from the Environmental Defense Fund, as well as technical support from Development Seed to enable OpenAQ to incorporate EDF AQDC data and data from 3 additional LCS partners on our platform as part of a two-phase pilot.

Our Pilot

What’s Next?

  • Continuing to engage in multi-stakeholder collaborations such as the Clean Air Catalyst) that will enable us to ingest and harmonize new varied data sources globally
  • Looking at new opportunities and partners to expand the LCS data available on our platform. If you would be interested in working with us to continue to bring new sources of data to our platform (of any kind), please reach out to Jeremy Taub at jeremy@openaq.org
  • Continue to learn from this pilot and get user feedback on the platform, various use cases, and new potential data and tools. When you use our data, we hope that you will reach out and share our feedback (via this survey)

Want to learn more?

We're making an open, real-time air quality data hub because we think it'll let people do amazing things. Want to help out? Find us at openaq.org.
