MegaSense enables smart city living by integrating multiple data sources to produce more consistent, accurate, and useful information than that provided by any individual data source in real time. In the context of air quality monitoring, MegaSense gathers and fuses spatially variable gas and particulate measurements from high-end scientific instruments, commercial air quality transmitters, dense low-cost sensor arrays, and consumer wearables utilizing Nb-IoT and 5G technologies. MegaSense platform analytics extract properties and attributes from the data, and following Artificial Intelliegnce based calibration, efficiently creates accurate and predictive knowledge structures. The knowledge structures provide evidence-based representations of pollution hot spots and can be used to intervene with harmful emission events and monitor the consequences of government policy interventions.

The goal of the MegaSense consortium of research and industry partners led by the University of Helsinki is to co-innovate research ideas, products and services and improve the architecture of smart city air quality monitoring. The MegaSense partners work together to develop 5G and secure Finnish leadership.

The credibility of MegaSense concept and potential is emerging through City of Helsinki Air Quality projects Urban Sense, and UIA HOPE, and thropugh International pilots.
