public class PassiveSampleTakingDeviceScanner
extends SampleTakingDeviceScanner

This is a base class for a passive sample taking device scanner, which does ignore the sample frequency and is triggered by the associated device to for sampling.
It does extend the sample taking device scanner to derive the SampleTakingDeviceScanner.takeSample() method, but overrides the start and stop methods to avoid spawning a timer task. It is intended to be used for the binary sensor types like light and proximity, which does rarely generate events.
