SparkFun Environmental Sensor Breakout - BME680 (Qwiic)

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, we recommend using Bosch's BSEC Software. If you need a more direct sensor we 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.

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

2 Programming

Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Great simple chip!

Hookup was very simple. So far the results seem accurate. I first used the Zanshin BME680 library which was quick and simple to setup. The VOC data is a little odd with that library though (technically it's a resistance value and not VOC). You can see the VOC value fluctuate up/down with the humidity and temp.

After that I used the BSEC library. This was difficult to setup but eventually I got it working. So far the results seem a little more accurate but I'll continue to test it. One note when using the BSEC library, the BSEC library is looking for the chip at a different i2c address than the sparkfun module is on. The sample code needs to be modified to use address 0x77. For example "Bsec.begin(0x77, Wire);
