LIS2DH: Motion Sensor Monitor¶
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.
This sample uses the LIS2DH, ST MEMS system-in-package featuring a 3D digital output motion sensor.
For more information about the LIS2DH motion sensor see http://www.st.com/en/mems-and-sensors/lis2dh.html.
Building and Running¶
The LIS2DH2 or compatible sensors are available on a variety of boards and shields supported by Zephyr, including:
- Actinius Icarus
- nRF52-PCA20020 (Thingy:52)
- ST STM32F3 DISCOVERY
- X-NUCLEO-IKS01A2: MEMS Inertial and Environmental Multi sensor shield
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¶
Actinius Icarus includes an ST LIS2DH12 accelerometer which supports the LIS2DH interface.

Building on nucleo_l476rg with IKS01A2 shield¶
The X-NUCLEO-IKS01A2: MEMS Inertial and Environmental Multi sensor shield includes an LSM303AGR accelerometer which supports the LIS2DH interface. This shield may also be used on other boards with Arduino headers.
