Such activities included: (1) identification of environmentally relevant gases associated with landfill site surface emissions and their concentration ranges; (2) technology scouting of the commercial sensors available on the market and selection of a first set of gas sensors suitable for this application, which were evaluated based on their cost, power consumption, and detection range, as declared by the manufacturer and/or by the scientific literature; (3) preliminary lab testing with relevant gases of the sensors identified in (2) for a first screening and further selection of a subset of sensors to be effectively implemented in the first version of the Sensors Toolbox.	cache/cet-14768.pdf	txt/cet-14768.txt
