	/***************************************************************************
	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. The device's I2C address is either 0x76 or 0x77.

	Adafruit invests time and resources providing this open source code,
	please support Adafruit andopen-source hardware by purchasing products
	from Adafruit!
