One sensor (MiCS-5914) is based on tungsten oxide, the other (MQ-3) on tin oxide. Both sensors were found to be sensitive to ethylene concentrations down to 10 ppm. Both sensors have significant response times; however, the tungsten sensor is the faster one. Sensor models are developed that predict the concentration of ethylene given the sensor output and the relative humidity. The MQ-3 sensor model achieves an accuracy of \u00b19.2 ppm and the MiCS-5914 sensor model predicts concentration to \u00b17.0 ppm. Both sensors are more accurate for concentrations below  50 ppm, achieving \u00b16.7 ppm (MQ-3) and 5.7 ppm (MiCS-5914).<\/jats:p>","DOI":"10.3390\/s151128088","type":"journal-article","created":{"date-parts":[[2015,11,6]],"date-time":"2015-11-06T11:12:15Z","timestamp":1446808335000},"page":"28088-28098","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["Quantitative Ethylene Measurements with MOx Chemiresistive Sensors at Different Relative Air Humidities"],"prefix":"10.3390","volume":"15","author":[{"given":"Matic","family":"Krivec","sequence":"first","affiliation":[{"name":"CTR Carinthian Tech Research AG, Europastrasse 12, A\u20139524 Villach, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gerald","family":"Gunnigle","sequence":"additional","affiliation":[{"name":"CTR Carinthian Tech Research AG, Europastrasse 12, A\u20139524 Villach, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"An\u017ee","family":"Abram","sequence":"additional","affiliation":[{"name":"Department for Nanostructured Materials, Jo\u017eef Stefan Institute, Jamova 39, SI\u20131000 Ljubljana, Slovenia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dieter","family":"Maier","sequence":"additional","affiliation":[{"name":"Philips Consumer Lifestyle Klagenfurt, Koningsbergerstrasse 11, A\u20139020 Klagenfurt, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roland","family":"Waldner","sequence":"additional","affiliation":[{"name":"Philips Consumer Lifestyle Klagenfurt, Koningsbergerstrasse 11, A\u20139020 Klagenfurt, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1532-5177","authenticated-orcid":false,"given":"Johanna","family":"Gostner","sequence":"additional","affiliation":[{"name":"Division of Medical Biochemistry, Medical University of Innsbruck, Center for Chemistry and Biomedicine, Innrain 80, A\u20136020 Innsbruck, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Florian","family":"\u00dcberall","sequence":"additional","affiliation":[{"name":"Division of Medical Biochemistry, Medical University of Innsbruck, Center for Chemistry and Biomedicine, Innrain 80, A\u20136020 Innsbruck, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Raimund","family":"Leitner","sequence":"additional","affiliation":[{"name":"CTR Carinthian Tech Research AG, Europastrasse 12, A\u20139524 Villach, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2015,11,6]]},"reference":[{"key":"ref_1","first-page":"1","article-title":"Selective Detection of Ethylene Gas Using Carbon Nanotube-based Devices: Utility in Determination of Fruit Ripeness","volume":"51","author":"Esser","year":"2012","journal-title":"Angew.
