Air quality sensing
summary
Claims deployment of 300 low-cost CO2 devices across Switzerland over LoRaWAN forming a country-scale network, plus an aircube with AlphaSense electrochemical sensors for NO2 mapping and an indoor ambient monitor (CO2, VOC, temp, humidity) running on 2×AAA batteries. Presents concrete results: raw sensor drift, reliance on in-field calibration and post-processing models, colocation against reference stations, city-scale mapping that improves with algorithms, and a live ~20-device indoor deployment with independent cross-comparison and award.
