The BMP3xx is the next-generation of sensors from Bosch, and is the upgrade to the BMP280 - with a low altitude noise as low as 0.1m and the same fast conversion time. And like the previous BMP280, you can use I2C or SPI. 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.

This sensor has a relative accuracy of 8 Pascals, which translates to about +-0.5 meter of altitude (compare to the BMP280's 12 Pascal/ +-1 meter). The datasheet sort of implies they intend this sensor to be used for drones and quadcopters, to keep altitude stable, but you could also use this for wearables or any project that wants to track height-above-sea-level. Note that for absolute height you'll still need to enter in the barometric pressure at sea level, if the weather changes, but that's true of every altimeter sensor that uses pressure. You can also measure temperature with +-0.5C accuracy.
