AQ low-cost sensors & Environmental Informatics

This is the web site of the Air Quality low-cost monitoring R&D activities of the Environmental Informatics Research Group at the Department of Mechanical Engineering, Aristotle University of Thessaloniki, Greece

We are running an AQ monitoring intercomparison exercise with instruments installed at the rooftop of building 12d at the Dept. of Mechanical Engineering, AUTh. The intercomparison started early 2018 and aims at the investigation of the performance of AQ sensor nodes under mediterranian conditions. The physical location of the installation is at 10 m height within the heart of the city, with a typical city traffic background (location map).
