A pointer value representing a handle used to identify an open instance of a logical sensor unit on a device
#include <sensor/sensor_api.h>
typedef void* sensor_handle_t;
A handle to the sensor is created by calling the sensor_open() function and is released by calling the sensor_close() function. A handle, when available, is similar to a file descriptor used to access the sensor. Various Sensor Frameworks calls use the handle to interact with the sensor.
