Las puntuaciones se concentran en valores altos, por lo que la posición dentro del catálogo suele ser más reveladora que el número por sí solo.
Evidence of impact / measured results1/3
Independent laboratory testing of the network's core SDS011 sensor found solid PM2.5 performance but 10–37% inter-unit error for PM10, and no controlled study of a specific policy outcome from the network was found, so impact evidence is real but limited.
Transferability / demonstrated replication3/3
The open-hardware kit has been independently rebuilt by volunteers worldwide, from roughly 5,000 units early on to networks spanning dozens of countries, entirely through unassisted replication.
Scalability3/3
The network grew from a 300-sensor target in Stuttgart to over 35,000 live stations tracked by the AQICN aggregator, one of the largest scale-ups of any citizen-sensing project.
Sustainability / continuity2/3
The project has operated continuously since 2015 on volunteer maintenance and open-source governance, though it lacks the institutional or government funding base that would guarantee long-term continuity.
Innovation3/3
Packaging a functioning particulate sensor into an approximately €30 solder-it-yourself kit was a genuine hardware and cost innovation that later citizen-sensing projects have copied.
Inclusiveness / equity2/3
Participation requires basic soldering skills and self-funding a kit, and available accounts describe a largely hobbyist/technical volunteer base rather than deliberate outreach to underserved communities.
Multi-stakeholder collaboration1/3
The project is coordinated as a loose, volunteer-run open-source community rather than through formal partnerships with government, academic or civil-society institutions.
