Ripening technology is based mainly on temperature control and gas regulation, with the proportion of ethylene being one of the key gas regulation parameters. A sensor\u2019s time domain response characteristic curve was obtained through the ethylene monitoring system. The first experiment showed that the sensor has good response speed (maximum of first derivative: 2.01714; minimum of first derivative: \u22122.01714), stability (xg: 2.42%; trec: 2.05%; Dres: 3.28%), and repeatability (xg: 20.6; trec: 52.4; Dres: 2.31). The second experiment showed that optimal ripening parameters include color, hardness (Change \u2160: 88.53%, Change \u2161: 75.28%), adhesiveness (Change \u2160: 95.29%, Change \u2161: 74.72%), and chewiness (Change \u2160: 95.18%, Change \u2161: 74.25%), verifying the response characteristics of the sensor. This paper proves that the sensor was able to accurately monitor changes in concentration which reflect changes in fruit ripeness, and that the optimal parameters were the ethylene response parameter (Change \u2160: 27.78%, Change \u2161: 32.53%) and the first derivative parameter (Change \u2160: 202.38%, Change \u2161: \u2212293.28%). Developing a gas-sensing technology suitable for fruit ripening is of great significance.<\/jats:p>","DOI":"10.3390\/s23115203","type":"journal-article","created":{"date-parts":[[2023,5,31]],"date-time":"2023-05-31T02:57:10Z","timestamp":1685501830000},"page":"5203","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Response Characteristics Study of Ethylene Sensor for Fruit Ripening under Temperature Control"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0395-928X","authenticated-orcid":false,"given":"Xiaoshuan","family":"Zhang","sequence":"first","affiliation":[{"name":"College of Engineering, China Agricultural University, Beijing 100083, China"}]},{"given":"Yuliang","family":"Li","sequence":"additional","affiliation":[{"name":"College of Engineering, China Agricultural University, Beijing 100083, China"}]},{"given":"Tianyu","family":"Hong","sequence":"additional","affiliation":[{"name":"College of Engineering, China Agricultural University, Beijing 100083, China"}]},{"given":"Srdjan","family":"Tegeltija","sequence":"additional","affiliation":[{"name":"Center for Identification Technology, Faculty of Technical Sciences, University of Novi Sad, Trg Dositeja Obradovica 6, 21000 Novi Sad, Serbia"}]},{"given":"Mladen","family":"Babi\u0107","sequence":"additional","affiliation":[{"name":"Center for Identification Technology, Faculty of Technical Sciences, University of Novi Sad, Trg Dositeja Obradovica 6, 21000 Novi Sad, Serbia"}]},{"given":"Xiang","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Engineering, China Agricultural University, Beijing 100083, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5558-677X","authenticated-orcid":false,"given":"Gordana","family":"Ostoji\u0107","sequence":"additional","affiliation":[{"name":"Center for Identification Technology, Faculty of Technical Sciences, University of Novi Sad, Trg Dositeja Obradovica 6, 21000 Novi Sad, Serbia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4311-1507","authenticated-orcid":false,"given":"Stevan","family":"Stankovski","sequence":"additional","affiliation":[{"name":"Center for Identification Technology, Faculty of Technical Sciences, University of Novi Sad, Trg Dositeja Obradovica 6, 21000 Novi Sad, Serbia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3583-9434","authenticated-orcid":false,"given":"Dragan","family":"Marinkovi\u0107","sequence":"additional","affiliation":[{"name":"Faculty of Mechanical Engineering, University of Ni\u0161, Aleksandra Medvedeva 14, 18000 Ni\u0161, Serbia"},{"name":"Faculty of Mechanical Engineering and Transport Systems, TU Berlin, Str. d. 17.
