gas sensor array dataset

The types of gases tested in this experiment are diverse, including not only single gases but also complex binary mixed gases. For single gases, nitrogen dioxide and ammonia, which are common in vehicle exhaust, were selected. For binary mixed gases, a mixture system of these two gases was chosen. Among them, the ammonia concentrations were set at 5 ppm, 10 ppm, 15 ppm, 20 ppm, 25 ppm, 30 ppm, 35 ppm, 40 ppm, 45 ppm, and 50 ppm respectively, while the nitrogen dioxide concentrations were set at 5 ppm, 10 ppm, 20 ppm, 30 ppm, 40 ppm, 50 ppm, 60 ppm, 70 ppm, 80 ppm, 90 ppm, and 100 ppm correspondingly. Such precise and comprehensive concentration settings can fully simulate the different states of these two main components in vehicle exhaust.
