SparkFun Environmental Sensor - BME688 (Qwiic)

The SparkFun BME688 Environmental Sensor is a breakout that combines a gas sensor with temperature humidity and barometric pressure sensing in a single package. The BME688's gas sensor 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 part-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!Solderless Environmental TrackingThe BME688 serves as a drop-in replacement for the BME680 and builds on the previous sensor by adding intelligent gas-scanning capabilities. While standard sensors simply detect the presence of gases this Bosch sensor generates unique profiles for different gas mixtures. Because we routed the default I2C interface to our solderless Qwiic connectors integrating this powerhouse sensor into your existing setup is incredibly fast and error-free. If you prefer a traditional breadboard layout or need the versatility of SPI communication all essential pins are conveniently broken out to standard 0.1-inch spaced headers.Key Performance CapabilitiesTo ensure your air quality monitoring projects are as precise and efficient as possible the BME688 Environmental Sensor provides several standout features:Intelligent Gas Sensing: Scans for VOCs VSCs (like hydrogen sulfide) and other gases in the part-per-billion range featuring an H₂S scanning F1 score of 0.92.Precision Measurements: Delivers highly accurate temperature (±1.0°C) relative humidity (±3%) and barometric pressure (±60Pa) data.Low Power Draw: Consumes just 0.15 µA in sleep mode and typically only 3.9 mA during a standard 10.8-second gas scan.AI Software Support: Compatible with the BSEC2 Arduino library and BME AI-Studio.Whether you are building a smart home climate monitor or a portable air quality tracker this sensor gives you all the essential environmental data you need without the complicated wiring.
