“…Portable, low-cost electronic noses (e-noses) based on an array of partially selective MOX sensors are widely used for gas sensing in many applications, including but not limited to landfill ( Perera et al, 2001 ; De Vito et al, 2011 ; Gębicki et al, 2014 ) and ship emission monitoring ( Yuan et al, 2020 ), chemical leakage detection in industrial sites ( Capelli et al, 2014 ; Bourne et al, 2020 ), early fire detection ( Young et al, 2003 ; Scorsone et al, 2006 ; Joseph et al, 2015 ), exploration of interested areas for emergency response or environmental monitoring ( He et al, 2019 ; Anyfantis et al, 2021 ), etc ( Monroy and Gonzalez-Jimenez, 2019 ; Burgués and Marco, 2020a ). In many real-world gas sensing related applications, gas detection comes as a fundamental task that recognizes the presence of gases by monitoring their concentration levels exceeding pre-defined thresholds.…”
