Sensor data event delivered via sensor_event_cb().

A sensor data is delivered as a structure, which contains the accuracy of the data, the time when the data was observed, and the data array. The data array is a fixed size float array, and the number of data fields stored in the array varies with the sensor type. For example, SENSOR_ACCELEROMETER reports 3-dimensional data, sensor_event_s::value_count is thus set to 3.
Note that, even if the data values are float, in some cases, it may contain one or more categorical data as in sensor_proximity_e.
