MPL3115A2, I2C Precision Altimeter
The MPL3115A2 is a compact piezoresistive absolute pressure sensor with an I2C interface. MPL3115A2 has a wide operating range of 20 kPa to 110 kPa, a range that covers all surface elevations on earth. The fully internally compensated MEMS in conjunction with an embedded high resolution 24-bit equivalent ADC provide accurate pressure (Pascals)/altitude (meters) and temperature (°C) data. The internal processing in MPL3115A2 removes compensation and unit conversion load from the system MCU, simplifying system design.
