The main challenge is the turbulent nature of gas dispersion and the response dynamics of the sensors. We propose a change point detection approach and evaluate it on individual gas sensors in an experimental setup where a gas source changes in intensity, compound, or mixture ratio. We also introduce an efficient sensor selection algorithm and evaluate the change point detection approach with the selected sensor array subsets.<\/jats:p>","DOI":"10.3390\/s121216404","type":"journal-article","created":{"date-parts":[[2012,11,27]],"date-time":"2012-11-27T11:14:30Z","timestamp":1354014870000},"page":"16404-16419","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":43,"title":["Detecting Changes of a Distant Gas Source with an Array of MOX Gas Sensors"],"prefix":"10.3390","volume":"12","author":[{"given":"Sepideh","family":"Pashami","sequence":"first","affiliation":[{"name":"Centre for Applied Autonomous Sensor Systems, \u00d6ebro University, \u00d6rebro SE-70182, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0217-9326","authenticated-orcid":false,"given":"Achim","family":"Lilienthal","sequence":"additional","affiliation":[{"name":"Centre for Applied Autonomous Sensor Systems, \u00d6ebro University, \u00d6rebro SE-70182, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marco","family":"Trincavelli","sequence":"additional","affiliation":[{"name":"Centre for Applied Autonomous Sensor Systems, \u00d6ebro University, \u00d6rebro SE-70182, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2012,11,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Baetz, W., Kroll, A., and Bonow, G.
