The BME688 is the first gas sensor with Artificial Intelligence (AI) and integrated high-linearity and high-accuracy pressure, humidity, and temperature sensors. It is housed in a robust yet compact 3.0 x 3.0 x 0.9 mm³ package and is specifically developed for mobile and connected applications where size and low power consumption are critical requirements. The gas sensor can detect Volatile Organic Compounds (VOCs), Volatile Sulfur Compounds (VSCs), and other gases such as carbon monoxide and hydrogen in the parts per billion (ppb) range. It features a gas scanner function that can be customized for specific detection cases using the BME AI-Studio tool.
