SparkFun Environmental Sensor (Qwiic) - BME680

The BME680 from Bosch is a powerful sensor capable of sensing humidity, barometric pressure, temperature and indoor air quality. The BME680 can communicate over SPI or I²C (default). The SparkX carrier board provides jumpers to select between communication protocols (SPI or I²C) as well as the ability to change the I²C address and remove the I²C pull up resistors. The carrier board also incorporates two Qwiic connectors so you can start talking to the board immediately - no soldering required!

While the BME680 is a very small IC, getting actual indoor air quality (IAQ) out of the BME680 is difficult. If you need a more direct sensor we recommend the SparkFun Environmental Sensor Combo which uses the CCS811 along side the BME280. Both sensors have robust libraries and a direct calculation of tVOCs and equivalent CO2.
