Product Descriptions

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 especially developed for mobile & 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 part per billion (ppb) range.

Additionally to all features of the BME680, the BME688 has a gas scanner function. In standard configuration, the presence of VSCs is being 

detected as indicator for e.g. bacteria growth. And the gas scanner can be customized

with respect to sensitivity, selectivity, data rate and power consumption as well. The BME AI-Studio tool enables customers to train the BME688 

gas scanner on their specific application, like in home appliances, IoT products

or Smart Home.

Product Applications

 Indoor air quality measurement

 Bad breath or spoiled food detection based on the measurement of volatile sulfur compounds, which are an indicator of bacteria growth

 Detection of unusual gases and smells, which might indicate for instance a leakage

 Diaper state detection, e.g. for baby care

 Early detection of odors & bad smells
