Air Quality Measurements Using Cheap Sensors
summary
Low-cost particulate sensors (from €15 chips to ~€700 units) can reliably detect large pollution spikes from fireworks — peaks around 2000 µg/m3, roughly 17–25 times background — and match the timing of official monitors. A community network of ~20–25 nodes streams data (about 25% via LoRa) into InfluxDB with public dashboards; devices use 3D‑printed or repurposed housings and need calibration and drift monitoring to yield actionable, high‑time‑resolution pollution evidence.
