/***************************************************************************
  This is a library for the BME280 humidity, temperature & pressure sensor
  Designed specifically to work with the Adafruit BME280 Breakout
  ----> http://www.adafruit.com/products/2650
  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!
