Frequency Analysis of Particulate Matter in Urban Environments under Low-cost Sensors
TL;DR: In this paper, the authors present a detailed analysis of PM signals' frequency behavior from an open-source dataset to correctly determine the maximum frequency needed to digitalize air pollution signals, which allows setting a period rate for estimating the concentration of particulate material with less resolution affectation and reducing the generation of data and energy consumption.

TL;DR: Electrical impedance measurements on different sensors are proposed in order to have a dataset of raw data to be used to perform classification of possible contaminants in water environment to demonstrate the technological advance in sensor integration and miniaturization leading to higher reliable results.
Are dense networks of low-cost nodes better at monitoring air pollution? A case study in Staffordshire
Louise Bøge Frederickson,Ruta Sidaraviciute,Johan A. Schmidt,Ole Hertel,Matthew,Stanley Johnson +5 more
TL;DR: In this paper , a network of 18 nodes using low-cost air pollution sensors was deployed in Newcastle-under-Lyme, Staffordshire, UK, in June 2020, where each node measured a range of species including nitrogen dioxide (NO 2 ), ozone (O 3 ), and particulate matter (PM 2 . 5 and PM 10 ).
