ExceptionCondition
PropertyNotImplementedExceptionIf this property is not available.
NotConnectedExceptionIf the device is not connected.
DriverExceptionAn error occurred that is not described by one of the more specific ASCOM exceptions. Include sufficient detail in the message text to enable the issue to be accurately diagnosed by someone other than yourself.
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 Fahrenheit.

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.
