Hi KjellzB,
I correct previous link, you could access it now. BME68X couldn't support to detect NO2/NOx. The gas sensor can detect Volatile Organic Compounds (VOCs), volatile sulfur compounds (VSCs) and other gases such as carbon monoxide and hydrogen in the part per billion (ppb) range. Detailed information, you could see it from https://www.bosch-sensortec.com/products/environmental-sensors/gas-sensors/bme688/
