Each concentration was tested in triplicate using three different sensors: TCA0, TCA1, and TCA3. Each concentration run includes three repetitions for each sensor.File formatcomma-separated values (csv)File naming conventionBME680_gas_sensor_[sensor number]_[ISO-UTCdatetime].csvBME continuous runDescriptionThis dataset includes data from a continuous run used for two-point sensor calibration. Data were collected from four sensors, each continuously recording data for 5 different concentrations of alpha-pinene.File formatcomma-separated values (csv)File naming conventionBME680_gas_sensor_[sensor number]_[ISO-UTCdatetime].csvBME validation testsDescriptionThis dataset contains data for 3 concentrations of alpha-pinene, recorded by three sensors: TCA0, TCA1, and TCA3.
