New BME280 Humidity Temperature Pressure Sensor (SPI or I2C)

Description:

This is an Air Pressure and Temperature sensor breakout board based on the BME280 from Bosch Sensortec.

The BME280 is the next-generation of sensors from Bosch, and is the upgrade to the BMP085/BMP180/BMP183 - with a low altitude noise of 0.25m and the same fast conversion time. It has the same specifications, but can use either I2C or SPI. The board breakouts both the I2C and SPI interface on the 6 pins including the GND and VCC, so you can choose which one to use. For simple easy wiring, go with I2C. If you want to connect a bunch of sensors without worrying about I2C address collisions, go with SPI.
