The MPL115A1 is a MEMS digital barometer that takes barometric pressure readings with a range of 50 to 115 kPa and an accuracy of ±1 kPa and provides the results over an SPI interface. This sensor also doubles as a temperature sensor that operates from -40 to 105 °C. The breakout board’s pins are spaced 0.1 apart making it easy to use with standard breadboards and 0.1" perfboards.
