SparkFun Environmental Sensor Breakout - BME680 (Qwiic) Hookup Guide
The SparkFun Environmental Sensor - BME680 (Qwiic) is a breakout for the 4-in-1 BME680 gas sensor from Bosch. The BME680 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 1"x1" breakout! The BME680 communicates over either I2C or SPI. As you would expect from the name, the BME680's I2C pins are broken out to a Qwiic connector so integrating it into the SparkFun Qwiic System is a breeze. Simply plug it into a Qwiic-enabled microcontroller and you're well on your way to making your own weather station.
To follow along with this guide you will need a microcontroller to communicate with the BME680. Below are a few options that come Qwiic-enabled out of the box:
If your chosen microcontroller is not already Qwiic-enabled, you can add that functionality with one or more of the following items:
You will also want at least one Qwiic cable to connect your sensor to your microcontroller.
