- A chemical detection platform composed of 14 temperature-modulated metal oxide semiconductor (MOX) gas sensors was continuously exposed during 3 weeks to dynamic mixtures of carbon monoxide (CO) and humid synthetic air in a gas chamber. The utilized sensors are commercially available by Figaro Engineering (7 units of TGS 3870-A04) and FIS (7 units of SB-500-12). The heater voltage of the sensors is modulated in the range 0.2-0.9 V in cycles of 20 and 25 s, following manufacturer recommendations. The acquired time series of the sensors and the measured values of CO concentration, humidity and temperature inside the gas chamber are provided. Each experiment consists on 100 measurements: 10 experimental concentrations uniformly distributed in the range 0-20 ppm and 10 replicates per concentration. Each replicate has a relative humidity randomly chosen from a uniform distribution between 15% and 75% r.h. A single experiment lasts 25 hours (100 samples x 15 minutes/sample) and was replicated on 13 working days spanning a natural period of 17 days. ##Attribute Information## The dataset is presented in 13 text files, where each file corresponds to a different measurement day. The filenames indicate the timestamp (yyyymmdd_HHMMSS) of the start of the measurements. Each file includes the acquired time series, presented in 20 columns: Time (s), CO concentration (ppm), Humidity (%r.h.), Temperature (oC), Flow rate (mL/min), Heater voltage (V), and the resistance of the 14 gas sensors: R1 (MOhm),R2 (MOhm),R3 (MOhm),R4 (MOhm),R5 (MOhm),R6 (MOhm),R7 (MOhm),R8 (MOhm),R9 (MOhm),R10 (MOhm),R11 (MOhm),R12 (MOhm),R13 (MOhm),R14 (MOhm) Resistance values R1-R7 correspond to FIGARO TGS 3870 A-04 sensors, whereas R8-R14 correspond to FIS SB-500-12 units. ##Relevant Papers## The description of the experimental setup and chemical detection platform can be found in [1-2].
