/***************************************************************************
|
||||
This is a library for the BME680 gas, humidity, temperature & pressure sensor
|
||||
|
||||
Designed specifically to work with the Adafruit BME680 Breakout
|
||||
----> http://www.adafruit.com/products/3660
|
||||
|
||||
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,
|
||||
