Qwiic Enviro Sensor - 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.
