Bosch BME690 Breakout Board – Smart Air Quality Measurement for Modern IoT Projects
The Bosch BME690 Breakout Board is a state-of-the-art 4-in-1 air quality sensor for precise environmental data acquisition in smart home, IoT, and industrial applications. In addition to temperature, humidity, and atmospheric pressure, the sensor also measures volatile organic compounds (VOCs) and other gases, enabling reliable assessment of indoor air quality.
The BME690 is based on the latest sensor generation from Bosch Sensortec and expands the functions of the well-known BME688 with increased robustness in high humidity and condensation. This makes the module ideal for demanding applications such as air quality monitoring, HVAC systems, kitchen exhaust, indoor climate monitoring, or intelligent building technology.
Thanks to integrated AI support and compatibility with the Bosch BME AI-Studio software, individual gas profiles can be trained and specific odor or air quality patterns can be recognized.
