Implements

IObservingConditionsDewPoint
Exceptions
ExceptionCondition
PropertyNotImplementedExceptionIf this property is not available.

Remarks

Optional property, can throw a PropertyNotImplementedException when the Humidity property also throws a PropertyNotImplementedException.

Mandatory property, must NOT throw a PropertyNotImplementedException when the Humidity property is implemented.

The units of this property are degrees Celsius. Driver and application authors can use the ConvertUnits(Double, Units, Units) method to convert these units to and from degrees Farenheit.

The ASCOM specification requires that DewPoint and Humidity are either both implemented or both throw PropertyNotImplementedExceptions. It is not allowed for one to be implemented and the other to throw a PropertyNotImplementedException. The Utilities component contains methods (DewPoint2Humidity(Double, Double) and Humidity2DewPoint(Double, Double)) to convert DewPoint to Humidity and vice versa given the ambient temperature.

This property should return a value between 0.0 and 100.0 where 0.0 = 0% relative humidity and 100.0 = 100% relative humidity.
