SparkFun BME280 Arduino Library

SparkFun CCS811/BME280 Combo (SEN-14348)

This library allows the user to:

• Read pressure in Pa
• Read temperature in C
• Read humidity in %RH

It also provides the following mathematical functions based from the above.

• Read temperature in F
• Read altitude in meters
• Read altitude in feet

Some examples include a circular buffer class for averaging.

Thanks to:

• calvin1564 for fixing a name collision
• LukaHitH for adding BMP280 support
• cdonate for adding burst read
• jdavid for integrating math.h
