Description :

• MPL3115A2 is a MEMS pressure sensor that provides Altitude data to within 30cm accuracy
  Outputs digitized by 24-bit ADC and transmitted over I2C for easy interface with most controllers
  Pressure output can be resolved with output in fractions of a Pascal
  Altitude can be resolved in fractions of a meter
  Also provides 12-bit temperature measurements in degrees Celsius
  Breakout board makes it easy to prototype by breaking out necessary pins to standard 0.1″ spaced header
  Board includes all passive components needed for device to function
  Simply connect to something that talks to I2C to get started.

Specifications:

• 1.95V to 3.6V Supply Voltage, internally regulated by LDO
  1.6V to 3.6V Digital Interface Supply Voltage
  Fully Compensated internally
  Direct Reading, Compensated:
  •Pressure: 20-bit measurement (Pascals)
