This data set is related to gas sensing, time-series classification. It has three columns: Time, I1, and Target. The Target column refers to the type of gas measured with the following classification:

•1 for Ammonia (NH₃)

•2 for Acetone (C₃H₆O) & Formaldehyde (CH₂O)

The data has been processed in a number of stages for accuracy and consistency. Raw data was first gathered using a Metal Oxide Semiconductor (MOS) sensor. After acquisition, the data were cleaned and processed, such as Savitzky-Golay filtering to remove noise or artifacts and smooth the signal.
