Air quality sensor provides environmental sensing with advanced AI

Mouser Electronics, Inc. now stocks the BME690 air quality sensor from Bosch. The four-in-one MEMS sensor effectively detects VOCs, VSCs, and other gases such as carbon monoxide and hydrogen. The sensor can also be employed for breath analysis and to reduce food waste through early spoilage detection. The air quality sensor supports a range of applications, including wearables, smart home appliances, and mobile and card devices.

The air quality sensor measures air pressure, gas, humidity, and temperature simultaneously. The sensor is an advanced version of the BME688 and BME680 devices optimized for use in environments with high levels of condensation. The BME690 sensor offers a simple drop-in upgrade, maintaining pin compatibility and the same dimensions (3mm x 3mm x 0.93mm3) as the previous models.

The air quality sensor supports plug-and-play operation and includes advanced AI features powered by Bosch Sensortec's BME AI-Studio software tool, which allows developers to train the sensor on their specific application. The sensor lowers power consumption by up to 50% compared to previous generations, making it ideal for wearables, asset tracking, and other battery-powered applications. The sensor is fully aligned with WELL and RESET standards for indoor air quality.

The BME690 air quality sensor is supported by the BME690 Shuttle Board, which is available to order from Mouser. Used in conjunction with the Bosch Application Board 3.x, the shuttle board allows evaluation of the signal outputs provided by the sensor itself or extra outputs generated by the BSEC Library for the sensor. The shuttle board enables easy access to the sensor pins via a simple socket and can be directly plugged into the Application Board 3.x.
