Journal ArticleDOI
Field calibration of a cluster of low-cost available sensors for air quality monitoring. Part A: Ozone and nitrogen dioxide
Laurent Spinelle,Michel Gerboles,Maria Gabriella Villani,Manuel Aleixandre,Fausto Bonavitacola +4 more
TL;DR: In this article, the performances of several field calibration methods for low-cost sensors, including linear/multi linear regression and supervised learning techniques are compared, and the accuracy of the predicted values was evaluated for about five months using a few indicators and techniques: orthogonal regression, target diagram, measurement uncertainty and drifts over time of sensor predictions.
Journal ArticleDOI
Field calibration of a cluster of low-cost commercially available sensors for air quality monitoring. Part B: NO, CO and CO2
Laurent Spinelle,Michel Gerboles,Maria Gabriella Villani,Manuel Aleixandre,Fausto Bonavitacola +4 more
TL;DR: In this paper, the performances of several field calibration methods for low-cost sensors, including linear/multi linear regression and supervised learning techniques, are compared and the accuracy of each regression method was evaluated on a five months field experiment at a semi-rural site using different indicators and techniques.
Proceedings ArticleDOI
Towards air quality indices in smart cities by calibrated low-cost sensors applied to networks
TL;DR: In this article, an experimental study focusses on air quality monitoring by low-cost and accurate sensors to provide a rank of air quality indices for citizens community in smart cities.
Proceedings ArticleDOI
Calibration of a cluster of low-cost sensors for the measurement of air pollution in ambient air
Laurent Spinelle,Michel Gerboles,Maria Gabriella Villani,Manuel Aleixandre,Fausto Bonavitacola +4 more
TL;DR: In this article, a clustered system of sensors able to measure O3, NO/NO2, CO and CO2 was used to compare the performance of several calibration methods, such as multivariate regression and neural networks.
