Class Thermistor

Thermistor temperature sensor object

Assembly: Thermistor.dll​
View Source​
Declaration
public abstract class Thermistor : PollingSensorBase<Temperature>, IObservable<IChangeResult<Temperature>>, ITemperatureSensor, ISamplingSensor<Temperature>, ISensor<Temperature>, ISensor, ISamplingSensor

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

Derived:
Meadow.Foundation.Sensors.Temperature.SteinhartHartCalculatedThermistor

Implements:

Properties​

AnalogInputPort​

The analog input port used to determine output voltage of the voltage divider circuit

View Source​
Declaration
protected IAnalogInputPort AnalogInputPort { get; }

NominalResistance​

The nominal resistance of the thermistor (e.g. 10kOhm for a 10k thermistor)

View Source​
Declaration
public abstract Resistance NominalResistance { get; }

NominalTemperature​

The nominal temperature for the nominal resistance, typically 25C

View Source​
Declaration
public virtual Temperature NominalTemperature { get; }

Temperature​

The temperature from the last reading

View Source​
Declaration
public Temperature? Temperature { get; }

Methods​

StartUpdating(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.

View Source​
Declaration
public override void StartUpdating(TimeSpan? updateInterval = null)
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.
         The default is 5 seconds. |

StopUpdating()​

Stops sampling the sensor

Declaration
public override void StopUpdating()
