E-nose data for pickled cabbage

6 categories of origin of pickled cabbage were collected by a homemade electronic nose device, which contained 16 sensors. 180 s sensor gas response values as data. The sampling rate is 10 Hz. Each sample provides 1800 × 16 points from 16 sensors. Down-sampling (Per 18 points) of all sensor signals data to100 x 16 points after filtering.

本数据集采用自制的16传感器电子鼻（electronic nose）设备，采集了6类不同来源的酸菜样本的气体响应信号，以180秒时长的传感器气体响应值作为原始数据。设备采样频率为10Hz，单一样本的16个传感器可生成1800×16个数据点。经滤波处理后，对所有传感器信号数据按每18个点进行下采样，最终将数据维度统一转换为100×16。
