"Odor discrimination with temperature modulated MOS gas sensors"

"This dataset comprises electronic nose signals for six volatile organic compounds (VOCs), collected using four commercial metal-oxide-semiconductor (MOS) gas sensor types from Figaro Engineering Inc. It is organized into three core subsets designed to systematically study the effects of experimental repetition, VOC concentration, sensor type diversity, and heating voltage modulation frequency. The dataset provides a comprehensive resource for developing and benchmarking signal processing, feature extraction, and machine learning models in the field of machine olfaction."
