:name: MPR Pressure Sensor
:relevant-api: sensor_interface
Get atmospheric pressure data from an MPR pressure sensor.
Overview
********
This sample application periodically (1Hz) measures atmospheric pressure in
kilopascal. The result is written to the console.

Wiring
******
This sample uses an MPRLS0025PA00001A sensor controlled using the i2c
interface. Connect **VIN**, **GND** and Interface: **SDA**, **SCL**.
Building and Running
********************
This project outputs sensor data to the console. It requires a sensor from the
MPR series.
It does not work on QEMU.
In the sample below the :ref:`arduino_due` board is used.
