Adafruit BMP280 Driver (Barometric Pressure Sensor) 
This driver is for the Adafruit BMP280 Breakout
About the BMP280
This precision sensor from Bosch is the best low-cost sensing solution for measuring barometric pressure and temperature. Because pressure changes with altitude you can also use it as an altimeter!
