The SparkFun BME688 Environmental Sensor is a breakout board that combines a gas-scanning sensor with temperature, humidity, and barometric pressure sensing for a complete environmental sensor in a single package. The gas sensor on the BME688 can detect a wide variety of volatile organic compounds (VOCs), volatile sulfur compounds (VSCs), and other gases, such as carbon monoxide and hydrogen, in the parts-per-billion (ppb) range. Combine that with precise temperature, humidity, and barometric pressure, and the BME688 can work as a completely standalone environmental sensor, all in a 1in. x 1in. breakout! The sensor communicates via either I2C or SPI. We've broken out the I2C pins to our Qwiic system, so no soldering is required to connect it to the rest of your system. If you would prefer, both the I2C and SPI pins are also broken out to standard 0.1in.-spaced pins. https://elecena.pl/product/20695256/sparkfun-environmental-sensor-bme688-qwiic 2022-04-08 https://elecena.pl/product/20695256/sparkfun-environmental-sensor-bme688-qwiic 2025-04-14
