How analysis works:
📷 Visual (Canvas CV) — samples pixels from the live frame, measures brightness, contrast, colour temperature, and grey/haze ratios to estimate visual AQI.
🌐 Sensor (Open-Meteo) — fetches real PM2.5/PM10/NO₂/O₃ data from the nearest CAMS station using your GPS location.
⚡ Combined — weighted average of both sources.
