.. zephyr:code-sample:: sensor_clock
   :name: Sensor Clock
   :relevant-api: sensor_interface

   Test and debug Sensor Clock functionality.

Overview

This sample application demonstrates how to select the sensor clock source and utilize the Sensor Clock API.

Building and Running

The sample below uses the :ref:`nrf52840dk_nrf52840` and :ref:`nrf52833dk_nrf52833` boards.

To run this sample, ensure the following configurations:

• Enable one of the Kconfig options: :kconfig:option:`CONFIG_SENSOR_CLOCK_COUNTER`, :kconfig:option:`CONFIG_SENSOR_CLOCK_RTC`, or :kconfig:option:`CONFIG_SENSOR_CLOCK_SYSTEM`.

Build and run the sample with the following command:

.. zephyr-app-commands::
   :zephyr-app: samples/sensor/clock
   :board: <board to use>
   :goals: build flash

Sample Output

The application will print the current sensor clock cycles and their corresponding time in nanoseconds.
