Hi SNAS,
Thanks for your inquiry. Bosch Sensortec’s gas sensors BME680 can detect a broad range of gases such as volatile organic compounds (VOC). Smoke is more prone to volatilization, while fog is a liquid and does not evaporate. BME680 is used for gas detection, and the detected gas needs to exchange air with the measurement unit of BME688. After a chemical reaction occurs, the resistance value is output. What are the components of the target smoke you want to detect?
