MPL115A1 Barometric Pressure Sensor Breakout Board

Note: This product has been replaced by the LPS331AP Pressure/Altitude Sensor Carrier with Voltage Regulator.

Overview

The MPL115A1 MEMS digital barometer carrier board from SparkFun takes ±1 kPa accurate pressure readings with a range of 50 to 115 kPa. The barometric pressure sensor makes the readings available via SPI. The pressure sensor’s average current consumption is 10μA at one measurement per second. The sensor 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.

See page 3 of the MPL115A1 datasheet (228k pdf) for information on how to take readings from this barometric pressure and temperature sensor. SparkFun also provides AVR ATMega328 C code for interfacing with the MPL116A1 (17k zip).

Features
