4-in-1 gas sensor with AI for an extensive range of gas sensing applications

03-03-2021 | Bosch Sensortec | Test & Measurement

Bosch Sensortec has released the BME688, the first air quality MEMS sensor that combines humidity, gas, temperature and barometric pressure sensing with innovative AI capability, essentially producing what it claims is the world’s smallest four-in-one air quality measurement solution. This single device allows customers to decrease their total cost of ownership, cut their development time and simplify design.


The new device is perfect for the latest, customised applications, including food spoilage detection and timely forest fire detection by detecting the gases present and tracking temperature and humidity changes. The sensor's AI features and the company’s new BME AI-Studio software tool make it easy for customers to quickly develop custom solutions for their particular use cases. To further cut time to market, it also offers an Adafruit-compatible development kit.


Built on the company's BME680 platform, the device offers an updated gas sensor facilitating an extended measurement range and sophisticated AI features. The gas sensor now detects the presence of multiple gases, including VOCs, VSCs and other gas types such as carbon monoxide and hydrogen, in the parts per billion range.






"The BME688 combines reliable high-precision sensors with wide-ranging gas detection and innovative AI capabilities in a single package,” says Dr Stefan Finkbeiner, CEO at Bosch Sensortec. “This enables our customers to rapidly develop the next generation of applications designed to improve well-being, lifestyle and sustainability.”
