The BME688 Environmental Sensor combines gas and air quality sensing with temperature, humidity and barometric pressure measurements, using I2C and dual Qwiic connectors for simple solder-free integration.
This is Soldered Electronics most advanced multi-purpose environmental sensor yet, built around the cutting-edge Bosch BME688. It combines precise environmental monitoring with gas analysis capabilities, measuring organic compounds (VOCs), volatile sulfur compounds (VSCs), carbon monoxide, and hydrogen in the parts-per-billion (ppb) range alongside temperature, humidity, and barometric pressure.
Our Arduino and MicroPython libraries focus on providing reliable environmental data and basic gas detection, but you can supercharge your project by using the Bosch BME-AI Studio software for advanced AI features. Our breakout communicates exclusively via the I2C interface (up to 3.4MHz), making integration straightforward with any microcontroller platform.
Designed for both industrial applications and makers, this breakout board includes dual Qwiic connectors for solderless, plug-and-play integration. Whether you are building an advanced air quality monitoring system, a smart HVAC controller, or conducting environmental research, the BME688 provides the precision and intelligence you need for comprehensive environmental sensing.
