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.<\/jats:p>","DOI":"10.3390\/s20236707","type":"journal-article","created":{"date-parts":[[2020,11,24]],"date-time":"2020-11-24T02:34:42Z","timestamp":1606185282000},"page":"6707","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Statistics of a Sharp GP2Y Low-Cost Aerosol PM Sensor Output Signals"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1602-5064","authenticated-orcid":false,"given":"Klemen","family":"Bu\u010dar","sequence":"first","affiliation":[{"name":"Jo\u017eef Stefan Institute, Jamova 39, 1000 Ljubljana, Slovenia"},{"name":"Jo\u017eef Stefan International Postgraduate School, Jamova 39, 1000 Ljubljana, Slovenia"},{"name":"Faculty of Mathematics and Physics, University of Ljubljana, Jadranska 19, 1000 Ljubljana, Slovenia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeanne","family":"Malet","sequence":"additional","affiliation":[{"name":"Institut de Radioprotection et de S\u00fbret\u00e9 Nucl\u00e9aire (IRSN), PSN-RES, SCA, 91190 Gif-Sur-Yvette, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2454-0389","authenticated-orcid":false,"given":"Luca","family":"Stabile","sequence":"additional","affiliation":[{"name":"Department of Civil and Mechanical Engineering, University of Cassino and Southern Lazio, 03043 Cassino, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1842-5181","authenticated-orcid":false,"given":"Jure","family":"Pra\u017enikar","sequence":"additional","affiliation":[{"name":"Institute Andrej Maru\u0161i\u010d, University of Primorska, Muzejski Trg 2, 6000 Koper, Slovenia"},{"name":"Faculty of Mathematics, Natural Sciences and Information Technologies, University of Primorska, Glagolja\u0161ka 8, 6000 Koper, Slovenia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2631-3158","authenticated-orcid":false,"given":"Stefan","family":"Seeger","sequence":"additional","affiliation":[{"name":"BAM\u2014Federal Institute for Materials Research and Testing, 12489 Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matja\u017e","family":"\u017ditnik","sequence":"additional","affiliation":[{"name":"Jo\u017eef Stefan Institute, Jamova 39, 1000 Ljubljana, Slovenia"},{"name":"Faculty of Mathematics and Physics, University of Ljubljana, Jadranska 19, 1000 Ljubljana, Slovenia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,11,24]]},"reference":[{"key":"ref_1","unstructured":"TSI Inc.
