Class AnalogWaterLevel

Represents an analog water level sensor

Assembly: Meadow.Foundation.dll​
View Source​
Declaration
public class AnalogWaterLevel : SamplingSensorBase<float>, IObservable<IChangeResult<float>>, ISamplingSensor<float>, ISensor<float>, ISensor, ISamplingSensor

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

Implements:
System.IObservable<Meadow.IChangeResult<System.Single>>, Meadow.Peripherals.Sensors.ISamplingSensor<System.Single>, Meadow.Peripherals.Sensors.ISensor<System.Single>, Meadow.Peripherals.Sensors.ISensor, Meadow.Peripherals.Sensors.ISamplingSensor

Properties​

AnalogInputPort​

AnalogInputPort connected to temperature sensor

View Source​
Declaration
protected IAnalogInputPort AnalogInputPort { get; }

LevelCalibration​

Calibration of water level

View Source​
Declaration
public AnalogWaterLevel.Calibration LevelCalibration { get; protected set; }

WaterLevel​

Water level

View Source​
Declaration
public float WaterLevel { get; protected set; }

Methods​

ReadSensor()​

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

View Source​
Declaration
protected override Task<float> ReadSensor()
Returns​

System.Threading.Tasks.Task<System.Single>

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 water level

View Source​
Declaration
public override void StopUpdating()

VoltageToWaterLevel(Voltage)​

Converts a voltage value to a level in centimeters, based on the current calibration values.

View Source​
Declaration
protected float VoltageToWaterLevel(Voltage voltage)
Returns​

System.Single

Parameters​
