Bosch Sensortec BME690 MEMS Indoor Air Quality Sensor
Optimized for high-condensation environments
Bosch Sensortec's BME690 is the latest-generation gas sensor that combines advanced monitoring capabilities with innovative artificial intelligence (AI) functionality. Built on the proven platform of Bosch’s BME688 and BME680 sensors, the BME690 offers pin compatibility and retains the compact 3 x 3 x 0.93 mm³ form factor, ensuring seamless integration as a drop-in upgrade.
The BME690 excels in monitoring indoor air quality, detecting Volatile Organic Compounds (VOCs), volatile sulfur compounds (VSCs), and gases such as carbon monoxide and hydrogen.
The BME690 has a gas scanner function also. 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.
