20.500.12556/RUL-134405 Statistics of a Sharp GP2Y low-cost aerosol PM sensor output signals In this work, we characterise the performance of a Sharp optical aerosol sensor model GP2Y1010AU0F. The sensor was exposed to different environments: to a clean room, to a controlled atmosphere with known aerosol size distribution and to the ambient atmosphere on a busy city street. During the exposure, the output waveforms of the sensor pulses were digitised, saved and a following offline analysis enabled us to study the behaviour of the sensor pulse-by-pulse. A linear response of the sensor on number concentration of the monosized dispersed PSL particles was shown together with an almost linear dependence on particle diameters in the 0.4 to 4 micrometer range. The gathered data about the sensor were used to predict its response to an ambient atmosphere, which was observed simultaneously with a calibrated optical particle counter. low-cost sensors aerosol sensors air quality sensors true false true Angleški jezik Ni določen Članek v reviji 2022-01-13 13:31:11 2022-01-13 13:31:11 2022-09-13 03:54:57 0000-00-00 00:00:00 2020 0 0 14 str. iss. 23, art. 6707 Vol. 20 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 53 1424-8220 10.3390/s20236707 40691715 RAZ_Bucar_Klemen_2020.pdf RAZ_Bucar_Klemen_2020.pdf 1 0405EEC7AA16EA50A7E66E64685514EF 6598c2b36e1fe0951420cb4c3c52caa841a3caded1f9dfe0e64a19e5d67c8222 346cb406-746e-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=152841 https://www.mdpi.com/1424-8220/20/23/6707 1 8259d548-746c-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=152840 Fakulteta za matematiko in fiziko 0 0 0
