MOx sensor dataset: Odour pulses of various concentration levels
<p><strong>Metal-Oxide (MOx) electronic nose (e-nose) sensor recordings, for odour pulses of various concentration levels </strong></p> <p>This data is a subset of a larger, yet unpublished dataset - collected by the following authors: Dennler N., Drix D., Warner T., Rastogi R., van Schaik A., Schaefer A., Schmuker M.</p> <p> </p> <p>The custom-made electronic nose used to collect the data is a successor of the device described in Drix & Dennler et al. [1]. It comprises four Metal Oxide (MOx) gas sensors operated at a constant heater voltage, and . </p> <p>The odour stimuli were provided by a multi-channel odour delivery device that is described in detail by Ackels et al. [2]. It offers a high temporal fidelity, which is achieved by combining high-speed gas valves, flow controllers, as well as short and narrow gas pathways. </p> <p>The data collection comprises of recordings where odourant headspace samples were embedded in constant airflow and presented to the e-nose. Data of four different odourants were used: Ethyl Butyrate (EB), Eucalyptol (Eu), Isoamyl Acetate (IA), and 2 - Heptanone (2H). EB, Eu and IA gases were diluted in mineral oil at a ratio of 1 : 5, and 2H was diluted in a ratio of 1:50. The delivered odour concentration was varied by modulating the valve shutter duty cycle, ensuring a linear relationship between five different concentration levels (E.g. C5 = 5 x C1). Fluctuations in flow during gas presentations were minimized by careful calibration.</p> <p>The filenames consist of the timestamp (in processor time), the gas identity, and a concentration level between 1 and 5. </p> <p> </p> <p>[1] D.
