Syntax

public abstract class PollingSensorBase<UNIT> : SamplingSensorBase<UNIT>, ISamplingSensor<UNIT> where UNIT : struct

Type Parameters

Name	Description
UNIT

Methods

StartUpdating(Nullable<TimeSpan>)

Starts updating the sensor on the updateInterval frequency specified.

This method also starts raising Updated events and notifying IObservable subscribers. Use the updateInterval parameter to specify how often events and notifications are raised/sent.

Declaration

public override void StartUpdating(TimeSpan? updateInterval = null)

Parameters

Type	Name	Description
System.Nullable<TimeSpan>	updateInterval	A TimeSpan that specifies how long to wait between readings. This value influences how often *Updated events are raised and IObservable consumers are notified. The default is 5 seconds.

Overrides

Meadow.Foundation.SamplingSensorBase<UNIT>.StartUpdating(System.Nullable<TimeSpan>)

StopUpdating()

Stops sampling the sensor

Declaration

public override void StopUpdating()

Overrides

Meadow.Foundation.SamplingSensorBase<UNIT>.StopUpdating()
