/***************************************************************************
This is a library for the BME680 humidity, temperature & pressure sensor
Designed specifically to work with the Adafruit BME680 Breakout
----> http://www.adafruit.com/products/XXXX
These sensors use I2C or SPI to communicate, 2 or 4 pins are required
to interface.
Adafruit invests time and resources providing this open source code,
please support Adafruit andopen-source hardware by purchasing products
from Adafruit!
