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.

To download. click the DOWNLOAD ZIP button, rename the uncompressed folder Adafruit_BME280. Check that the Adafruit_BME280 folder contains Adafruit_BME280.cpp and Adafruit_BME280.h
Place the Adafruit_BME280 library folder your arduinosketchfolder/libraries/ folder. You may need to create the libraries subfolder if its your first library. Restart the IDE.
