25 /** \example example_service_sensor_off.c
26  * @brief This is an example on how to power off the sensor between measurements using the Service API
27  * @n
28  * The example executes as follows:
29  * - Create a configuration
30  * - Create a processing instance using the previously created configuration
31  * - Create a sensor instance
32  * - Power on sensor
33  * - Prepare sensor
34  * - Perform a sensor measurement and read out the data
35  * - Power off sensor
36  * - Process the measurement
37  * - Destroy the sensor instance
38  * - Destroy the processing instance
39  * - Destroy the configuration
