Temperature

Current Temperature

Methods

ReadSensor()

Convenience method to get the current temperature. For frequent reads, use StartSampling() and StopSampling() in conjunction with the SampleBuffer.

View Source

Declaration

protected override Task<Temperature> ReadSensor()

Returns

System.Threading.Tasks.Task<Meadow.Units.Temperature>: The temperature averages of the given sample count### StartUpdating(TimeSpan?) Starts continuously sampling the sensor.

This method also starts raising Changed events and IObservable subscribers getting notified. Use the readIntervalDuration parameter to specify how often events and notifications are raised/sent.

View Source

Declaration

public override void StartUpdating(TimeSpan? updateInterval)

Parameters

Type	Name	Description
System.Nullable<System.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. |

StopUpdating()

Stops sampling the temperature

View Source

Declaration

public override void StopUpdating()

VoltageToTemperature(Voltage)

Converts voltage to Temperature

View Source

Declaration

protected Temperature VoltageToTemperature(Voltage voltage)

Returns

Meadow.Units.Temperature: Temperature

Parameters

Type	Name
Meadow.Units.Voltage	voltage

Dispose()

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

View Source

Declaration

public void Dispose()

Dispose(bool)

Dispose of the object

View Source

Declaration

protected virtual void Dispose(bool disposing)

Parameters

Type	Name	Description
System.Boolean	disposing	Is disposing
