Class Alspt19315C

Represents an Alspt19315C analog light sensor

Assembly: Alspt19315C.dll​
View Source​
Declaration
public class Alspt19315C : SamplingSensorBase<Voltage>, IObservable<IChangeResult<Voltage>>, ISamplingSensor<Voltage>, ISamplingSensor, IVoltageSensor, ISensor<Voltage>, ISensor

Inheritance: System.Object -> Meadow.Foundation.ObservableBase<UNIT>

Implements:
System.IObservable<Meadow.IChangeResult<Meadow.Units.Voltage>>, Meadow.Peripherals.Sensors.ISamplingSensor<Meadow.Units.Voltage>, Meadow.Peripherals.Sensors.ISamplingSensor, Meadow.Peripherals.Sensors.IVoltageSensor, Meadow.Peripherals.Sensors.ISensor<Meadow.Units.Voltage>, Meadow.Peripherals.Sensors.ISensor

Properties​

Voltage​

The current voltage reading of the sensor

View Source​
Declaration
public Voltage? Voltage { get; protected set; }

Methods​

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​
TypeNameDescription
System.Nullable<System.TimeSpan>updateIntervalA 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 sensor

View Source​
Declaration
public override void StopUpdating()

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<Voltage> ReadSensor()
Returns​

System.Threading.Tasks.Task<Meadow.Units.Voltage>: A float value that's an average value of all the samples taken.### ReadVoltage() Reads the current voltage of the sensor

View Source​
Declaration
public ValueTask<Voltage> ReadVoltage()
Returns​

System.Threading.Tasks.ValueTask<Meadow.Units.Voltage>
