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