MPL3115A2 Pressure/Altitude Sensor Features
The MPL3115A2 pressure and altitude sensor is a MEMS pressure sensor that generates altitude data. The sensor outputs are converted to digital data by high-resolution 24bit ADC and transfer over I2C, which means that this module easily communicates with most microcontrollers. The unit of pressure and height is Pascal and meter respectively. The module also measures 12-bit temperature in degrees Celsius.
