/***************************************************************************
|

|
|
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,
|
||
|
|
please support Adafruit and open-source hardware by purchasing products
|
||
|
|
from Adafruit!
