           proximity sensor.

    \target QProximityReading_Units
    The proximity sensor can only indicate if an object is close or not.

    The distance at which an object is considered close is device-specific. This
    distance may be available in the QSensor::outputRanges property.

    This class also features a reading() function that returns a QProximityReading instead of a QSensorReading.
