Metane\Propane semiconductor sensor’s data
The data set represents real measurements of semiconductor gas sensors.
Data folder structure:
Date of measurement -> Gas type -> Gas concentration -> Data file.
The data file name S1_05_100.csv contains folowwing information:
S1the type of measuring sensor;05the serial number of this measurement on this day relative to other measurements;100gas concentration (ppm).
File structure:
- Rows — samples; Columns — features. No indexes and headers;
- 1 Measurement = 2 consecutive rows (temperature and resistance of the gas sensor);
- Duration = 1 minute with a sampling frequency of 10 Hz;
- The sequence of rows corresponds to the sequence of measurements over time.
It is strongly recommended to skip the first 5 measurements (10 rows) due to distortion observed when measuring a new type of gas was started.
