Detailed Description▲
The QDistanceReading class holds distance reading in cm from the proximity sensor. Note: Some proximity sensor only support two values for distance, a near and far value. In this case, the sensor should report its maximum range value to represent the far state, and a lesser value to represent the near state.
QDistanceReading Units▲
