Synergetic laser-electronic sensor array dataset
Description
This dataset contains experimental data from a photonic-collaborative sensor array. The array is composed of three distinct types of sensors, including one laser sensor and two metal oxide semiconductor (MOX) sensors. The laser sensor (model: YZ-MF-100L), manufactured by Yizhuo (China), is primarily used for detecting methane (CH₄) gas, with a concentration range of 0%-100% LEL (Lower Explosion Limit). The two MOX sensors, GM-602 and GM-702, are both produced by Winsen (China). The GM-602 sensor is designed for detecting multiple gases, including hydrogen sulfide (H₂S), ammonia (NH₃), methane (CH₄), and ethanol (C₂H₅OH), with a concentration range of 0-50ppm. The GM-702 sensor is specifically used for detecting carbon monoxide (CO), methane (CH₄), and hydrogen (H₂), with a concentration range of 0-5000ppm. The sensor array is configured to monitor and analyze the concentration variations of specific gases, providing accurate environmental monitoring data.

Steps to reproduce
The experiment lasted for 500 seconds, with the first 50 seconds used to establish the stability of the sensor array. At the 50th second, a mixture of multiple gases was introduced into the gas chamber and maintained for 200 seconds. The gas removal process began at the 250th second, completing the entire testing process. After each test, the system was idle for 20 minutes before starting the next test cycle. The measurement ranges were set as follows: methane (CH4) concentration range from 0-10000 ppm, carbon monoxide (CO) concentration range from 0-2500 ppm, and hydrogen sulfide (H2S) concentration range from 0-25 ppm. Five different concentrations were used for each gas. A total of 186 data points were collected.
