MPL3115A2 I2C Barometric Pressure, Altitude, Temperature Sensor

The MPL3115A2 communicates information on pressure, altitude and temperature (the latter with an accuracy of 1°C).

Uses of the Barometric Pressure Sensor

Having a barometric pressure sensor that also provides information on altitude and temperature can be extremely useful for all your UAV navigation systems. The barometric sensor will also have its place in your weather station projects, and in your GPS and navigation assistance systems.
