MPL3115A2 - Barometric Pressure / Altitude / Temperature Sensor 5 mega pixel 3V power supplyThis pressure sensor from Freescale is a great low cost sensing solution for precision measurement of barometric pressure and altitude. The MPL3115A2 has a typical 1. 5 Pascal resolution, which can resolve altitude at 0. 3 meters (compare to the BMP180 which can do 0. 17m). It has the same upsides compared to BMP280, such as interrupt outputs for ultra low power usage, and its also a heck of a lot easier to read altitude with a built in altimeter
