BME690

Digital low power temperature, humidity, pressure and gas sensor with AI

The BME690 is the 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 BME690 is more robust to previous products and can be used in high condensation

applications. The gas sensor can detect Volatile Organic Compounds (VOCs), volatile sulfur compounds (VSCs)

and other gases such as carbon monoxide and hydrogen.

Same as BME688, the BME690 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 BME690 gas scanner on their specific application, like in home appliances, IoT products or Smart Home.

Typical 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 or fire

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

 Early detection of odors & bad smells

 Wildfire detection

Target Devices

 Handsets such as mobile phones, tablet PCs, GPS devices

 Wearables e.g. smart watches or connected sensors

 Mobile / care devices like toothbrushes or breath checkers

 Smart home devices, e.g. smart speakers, connected sensors or lamps

 Room climate sensors & weather stations

 Home appliances

 Gaming, e.g. flying toys

 Connected devices, for instance for asset tracking or surveillance

 Sensor networks / sensor nodes
