Adafruit BME280 Humidity/Pressure/Temperature sensor

This is a library for the Adafruit BME280 Humidity, Barometric Pressure + Temp sensor

Designed specifically to work with the Adafruit BME280 Breakout

These sensors use I2C or SPI to communicate, up to 4 pins are required to interface

Use of this library also requires Adafruit_Sensor to be installed on your local system.
