Hi poster,
Thank for your inquiry. BME688 supports detecting different VOCs, and BME AI-Studio software supports training the data recorded by BME688 to detect gases. For actual gas detection, sensor data is usually collected in actual gas environments, trained through BME AI-Studio, and tested in actual environments. There are many types of gases that BME688 supports detection, but we have not conducted pipeline natural gas testing, so users need to try it in specific environments. All BME688 docs & software for your reference: https://www.bosch-sensortec.com/software-tools/software/bme688-software
