.. zephyr:code-sample:: mpr
   :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 :zephyr:board:`arduino_due` board is used.

   :zephyr-app: samples/sensor/mpr
   :board: arduino_due
   :goals: build flash
