25 /** \example example_detector_presence_low_power_off.c
26 * @brief This is an example on how to disable the sensor and put the system in a low power state between measurements
27 * @n
28 * The example executes as follows:
29 * - Create a presence configuration
30 * - Create a sensor instance
31 * - Enable sensor
32 * - Create a detector instance
33 * - Calibrate the sensor
34 * - Prepare the detector
35 * - Loop forever:
36 * - Enable sensor
37 * - Prepare a sensor
38 * - Perform a sensor measurement and read out the data
39 * - Disable sensor
40 * - Process the measurement and get detector result
41 * - Put the system in deep sleep for a specified amount of time
42 * - Destroy the configuration
43 * - Destroy the detector instance
44 * - Destroy the sensor instance
