.. zephyr:code-sample:: lis2dh
:name: LIS2DH Motion Sensor
:relevant-api: sensor_interface
Get accelerometer data from an LIS2DH sensor (polling & trigger mode).
Overview
********
This sample application periodically reads accelerometer data from the
LIS2DH sensor (or the compatible LS2DH12, LIS3DH, and LSM303DLHC
sensors), and displays the sensor data on the console.
Requirements
************
This sample uses the LIS2DH, ST MEMS system-in-package featuring a 3D
digital output motion sensor.

Building and Running
********************
The LIS2DH2 or compatible sensors are available on a variety of boards
and shields supported by Zephyr, including:
* :zephyr:board:`actinius_icarus`
* :zephyr:board:`thingy52`
* :zephyr:board:`stm32f3_disco`
* :ref:`x-nucleo-iks01a2`
See the board documentation for detailed instructions on how to flash
and get access to the console where acceleration data is displayed.
Building on actinius_icarus
===========================
:zephyr:board:`actinius_icarus` includes an ST LIS2DH12 accelerometer which
supports the LIS2DH interface.

Building on nucleo_l476rg with IKS01A2 shield
=============================================
The :ref:`x-nucleo-iks01a2` includes an LSM303AGR accelerometer which
supports the LIS2DH interface. This shield may also be used on other
boards with Arduino headers.
