Urban air quality mesh
Live telemetry plus traffic and weather context. The goal is not pretty charts. It is the causal story. When congestion spikes gases spike. When wind stalls pollution stays.
What this demo tests
- Traffic hotspots correlate with NO2 and CO spikes.
- Low wind increases accumulation even at similar traffic levels.
- Time windows show when exposure risk climbs.
The dashboard still works if real nodes go silent.
Intent
Show how congestion and dispersion shape urban pollution in near real time.
Sources
Mesh sensors, traffic context, and weather snapshots. The UI uses local API routes so it can run before a backend exists.
Outputs
Live KPIs, grid heatmap, node health table, and short correlation notes.
Cluj Napoca urban air quality mesh
Live fusion of LoRa sensor telemetry and city scale weather context.
Intent: show congestion and pollution impact for the thesis defense.

City context and intent
This dashboard correlates air quality, traffic congestion, and weather conditions to explain how mobility patterns impact Cluj Napoca. It is a thesis defense view that connects sensor telemetry to routing and policy context.
Correlation focus
NO₂ + NOx + O₃ + traffic density
