For details about how the sensor works, see QLightReading.
See also QLightReading.
fieldOfView : const qreal
This property holds a value indicating the field of view.
This is an angle that represents the field of view of the sensor.
Not all light sensor support retrieving their field of view. For sensors that don't support this property, the value will be 0. Whether the field of view is supported can be checked with QSensor::isFeatureSupported() and the QSensor::FieldOfView flag.
