“…In research presented by Vuka and coworkers [ 164 ], the six metal oxide sensors and an ultrasonic anemometer wind sensor were employed to find the origin of hexane gas. The sensors were integrated in a mobile robot in a Gaussian regression domain approach with an active search algorithm (gas source localization, GSL) learned to find the gas-polluting gas source.…”

“…However, some researchers have estimated LOD in MOXs sensors using alternative approaches [ 174 ]. In [ 164 ], ten MOX sensors (FIS SB-500-12 and FIGARO TGS 3870-A04, five of each type) were used to detect CO in varying air humidity (20–80% RH) at a constant airflow of 1 l/min. It was shown that at low concentrations (less than 50 ppm), the MOX signals could be fitted with linear models and that the homoscedasticity condition was met; moreover, cross-sensitivity to moisture was the major factor in reducing the LOD of MOX sensors.…”

“…Simulated experiments were conducted to find the optimal values of the parameters, b and g. The environments are shown in Figure 18. The geometric maps used for the experiments are of real-world environments in which we carried out different mobile robot olfaction experiments in our previous work: (1) a campus corridor with stairs and sitting places (Arain et al, 2015a(Arain et al, , 2016Polvara et al, 2018;Vuka et al, 2017); (2) an outdoor forest area (Arain et al, 2015a;Hernandez Bennetts et al, 2013; (3) an industrial foundry where bronze bearings are produced (Schaffernicht et al, 2017); and (4) an industrial foundry where high-volume products are being cast (Hernandez Bennetts et al, 2016).…”

“…Metal oxide semiconductor (MOX) gas sensors are characterized by high sensitivity, fast response, and low cost. Those characteristics make their application very promising in different fields, such as agri-food quality and safety [1][2][3][4][5], environmental monitoring [6][7][8], home security [9][10][11], and human health [12][13][14] among the most investigated. Although these features make MOX sensors one of the most promising technologies of recent years, their diffusion is limited due to some disadvantages.…”
