First, we chose the first ten seconds of non-steady state (rapid detection mode) sensor data as the dataset, rather than waiting for the electronic nose to stabilize during the detection process. This was carried out in the hope of improving the detection efficiency of the e-nose and to demonstrate that the e-nose can collect gasses efficiently in rapid detection mode. The random forest approach is then used to optimize and reduce the dataset\u2019s dimensionality, filtering critical features and improving the electronic nose\u2019s classification capacity. Finally, this study builds an electronic nose humidity compensation system to compensate for the datasets generated via rapid real-time detection, efficiently correcting the deviation of the sensor response caused by humidity variations. This method enhanced the average resolution of the electronic nose in this trial from 87.7% to 99.3%, a 12.4% improvement, demonstrating the efficacy of the humidity compensation system based on rapid detection for the electronic nose. This strategy not only improves the electronic nose\u2019s anti-drift and classification capabilities but also extends its service life, presenting a new solution for the electronic nose in practical detecting applications.<\/jats:p>","DOI":"10.3390\/s24185881","type":"journal-article","created":{"date-parts":[[2024,9,10]],"date-time":"2024-09-10T10:20:10Z","timestamp":1725963610000},"page":"5881","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Electronic Nose Humidity Compensation System Based on Rapid Detection"],"prefix":"10.3390","volume":"24","author":[{"given":"Minhao","family":"Cai","sequence":"first","affiliation":[{"name":"College of Engineering, South China Agricultural University, Guangzhou 510642, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sai","family":"Xu","sequence":"additional","affiliation":[{"name":"Institute of Facility Agriculture, Guangdong Academy of Agricultural Sciences, Guangzhou 510640, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xingxing","family":"Zhou","sequence":"additional","affiliation":[{"name":"Institute of Facility Agriculture, Guangdong Academy of Agricultural Sciences, Guangzhou 510640, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huazhong","family":"Lu","sequence":"additional","affiliation":[{"name":"Guangdong Academy of Agricultural Sciences, Guangzhou 510640, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"130727","DOI":"10.1016\/j.snb.2021.130727","article-title":"A novel WWH problem-based semi-supervised online method for sensor drift compensation in E-nose","volume":"349","author":"Liang","year":"2021","journal-title":"Sens.
