Microsensor Air Quality Network

← Back to Environment applications

Street-level urban air quality monitoring with 15 microsensors in four provinces; data tracking and maintenance.

Monitoring at street level

Reference stations measure with high accuracy, but placing one at every location is not practical. Microsensors form a denser network, showing the effect of traffic and local sources within a city.

Keeping the network reliable

  • Comparing sensor readings with reference measurements
  • Accounting for temperature and humidity effects
  • Monitoring sensor life and data gaps
  • Interpreting results as a complement to reference measurement, not a replacement

See environmental IoT monitoring systems for more on this approach.
