weather sensor help!?!

funinalaska

Does anyone know of a outdoor humidity sensor that works in extremely cold temps?

I need something that is moisture save and that will work at temperatures well below -40

I need it to have a minimum 2M watertight lead.

Right now for temperature I am using the DS18B20

It works for temperature but have now discovered I also need humidity readings as well.

    I am beginning to think that I will just be better off figuring out how to access the airport's weather data. It is about 1/2 mile from me but their temperature readings are consistently 2 to 5 degrees F colder that readings I get here at my house. I blame it on the fact that the airport's weather station is a good 100 yards away from an structure or any form of wind or weather break. I have not yet figured out how to get my ethernet shield to do all the tasks I wish to ask from it, but it seems that sourcing their data from the METAR service will be much more reliable for humidity and wind speed than to implement my own sensors for those variables.

    We are getting to the time of year where the weather here is beginning to push the limits of some sensors and if this fall is any indication we could be in for a very wild ride this winter.

    Thank you all for the help and for the advise.

    I have many other questions but for now I will need to set aside this project for the holidays as I will be leaving this cold place for a still cold but not quite as harsh place at least for a few days.
