Kumar Gala 5d36157c7c sensors: Remove unnecessary Kconfig setting of sensors Sensor Kconfig sybmols should be enabled if CONFIG_SENSOR=y and the devicetree node for the sensor is enabled. We can remove explicitly enabling specific sensor drivers in .conf files. Signed-off-by: Kumar Gala <galak@kernel.org>		2022-07-25 15:18:56 +02:00

MPR Pressure Sensor
###################

Overview
********

This sample application periodically (1Hz) measures atmospheric pressure in
kilopascal. The result is written to the console.

References
**********

- MPR: https://sensing.honeywell.com/micropressure-mpr-series

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.
