Abstract :
[en] The use of low-cost air quality sensors to evaluate personal exposure, complement a monitoring network or perform real-time data assimilation is spreading. Although some laboratories and project consortiums have set up their own procedures to assess the performan ce of such systems and although the CEN TC264 WG42 is preparing two standards on that topic, so far the only European reference remains the Guidance for the Demonstration of Equivalence of Ambient Air Monitoring Methods [3] that holds for any kind of device, whether it costs 100 or 10 000 €. This short paper presents the application on a recent data set of some generic statistical tests and the demonstration of equivalence to evaluate the performance of various air quality nodes. The demonstration of equivalence uses an orthogonal regression whereas a majority of papers present a linear model based on total least square. We present the measurement campaign set up, the devices and their main characteristics, as well as the metrics used to assess their performance. We show and discuss the results, whereas in Section 4, we draw our conclusion.
