The BMP280 Digital Sensor features I2C and SPI interfaces which is a significant advantage over BMP180. In addition, the BMP280 temperature and barometric air pressure sensor has many improved features that make it much better than the older versions. This is the 3.3V variant of the BMP280 digital sensor.
