The SparkFun BME680 Environmental Sensor is a breakout that combines a gas sensor with temperature, humidity and barometric pressure sensing for a complete environmental sensor in a single package. The gas sensor on the BME680 can detect a wide variety of volatile organic compounds (or VOC for short) to monitor indoor air quality. Combine that with precise temperature, humidity, and barometric pressure and the BME680 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 but if you would prefer, both the I²C and SPI pins are also broken out to standard 0.1in.-spaced pins.

Note: Getting actual indoor air quality (IAQ) from the BME680 can be difficult. If you would like to use the BME680 for precise IAQ measurements, Sparkfun recommend using Bosch's BSEC Software. If you need a more direct sensor Sparkfun recommend the SparkFun Environmental Sensor Combo which uses the CCS811 alongside the BME280.

The SparkFun Qwiic connect system is an ecosystem of I²C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can't hook it up wrong.
