    Altitude/Pressure Sensor Board, MPL3115A2, 3.3V
    SEN-11084
    The MPL3115A2 is a MEMS pressure sensor that provides altitude data to within 30cm (with oversampling enabled). The sensor outputs are digitized by a high-resolution 24-bit ADC and transmitted over I2C, so it's easy to use with most controllers. Pressure output can be resolved with output in fractions of a Pascal, and altitude can be resolved in fractions of a meter. The device also provides 12-bit temperature measurements in degrees Celsius.
    This breakout board makes it easy to prototype using this tiny device by breaking out the necessary pins to a standard 0.1"-spaced header. The board also has all of the passive components needed to get the device functioning, so you can simply connect it to something that talks I2C and get to work.
    Note however that this sensor uses the I2C repeated-start condition, so you should be sure that your microcontroller supports this — e.g. Arduino does, but
    Raspberry Pi
    does not.
    Another module with the MPL3115A2 sensor is available, in mikroBUS form factor. See the

    MPL3115A2 Sensor Features
    1.95V to 3.6V Supply Voltage, internally regulated by LDO
    1.6V to 3.6V Digital Interface Supply Voltage
    Fully compensated internally; provides direct readings without software
    Pressure reading: 20-bit measurement (Pascals), typical accuracy ±0.05kPa
    Altitude reading: 20-bit measurement (meters), typical accuracy ±0.3m
    Temperature reading: 12-bit measurement (°C), typical accuracy ±3°C
    Programmable Events
    Autonomous Data Acquisition
    32-sample FIFO
    Ability to log data up to 12 days using the FIFO
    Data acquisition rates of 1 second to 9 hours
    I2C digital output interface (operates up to 400 kHz)
    Note: The Pressure and Altitude readings are the same measurement, just expressed in different ways.
