Conception and deployment of the APOLLINE sensor network for IAQ monitoring

The long-term study of air quality inside buildings in the presence of occupants requires the deployment of low-cost instruments capable of measuring the most concerning pollutants, without nuisance to the occupants. Several laboratories within the University of Lille, France, have united their expertises within the APOLLINE project (Air Pollution and Individual Exposure). They have designed a complete infrastructure for IAQ research and education, based on chemical (NO, NO₂, O₃, CO, CO₂, COV, granulometry of PM 0.4-16 μm) and physical (P, T, RH, light, sound) sensor nodes. The nodes continuously send raw measurements through Ethernet or various wireless technologies to the APISENSE® cloud platform operated by Inria, for offsite realtime visualization and analysis. The network was successfully deployed since July 2018 within the buildings of University of Lille, with interesting results on the pollution levels and occupancy patterns. (paper)
