Hi, Happy New Year!
First time poster. I'm planning on building a weather station with the wind vane, anemometer, rain-gauge, temperature and humidity and possibly even the lightening detector. I have many questions but here is the first one.
I live in Central Minnesota and winter temperatures can get brutally cold - last night was down to -7°F (-22°C). Wind chill was around -20°F. And this is not the coldest we will get this winter.
Here's my question - what is the lowest operating temperature for all the components, both mechanical and electronic. I could probably fashion some sort of weather proof/resistant case for the electronics but the mechanical components will always be exposed. Are they going to crack or break in this cold? Will ice forming in the rain gauge break it? I really don't want to bring the weather station in every winter, nor do I want to replace parts all the time.
Any suggestions or advice are appreciated.

If you are aren't using Solar, then I don't thing -7 degrees F is going to give you any problem at all. Wind chill won't make any difference.
Regarding the possibility of ice destroying the rain gauge, I don't think so. It just won't read the precipitation. If you heat the bucket up you can measure the water content of the snow falling (but not the number of inches of snow!).
Heavy icing on the wind vane or anemometer is a possibility. Here in western Washington, we have never lost a system. We did lose a system in the Caribbean to a hurricane!

@bp, Thank you for the quick reply. No - I will not be using a solar panel - they do not survive our winters Also, I'm not planning on measuring snowfall. The two things that worry me are: - Our winter lows can get down to -20°F (-29°C) in an average year. I hope the plastics don't get brittle at those temperatures.
- In our Fall and Spring, we go through a daily thaw / freeze cycle. Any water in and on the station will freeze but I hope it will not crack the plastic.
I would love to hear from others in the northern mid-west states or Manitoba and Saskatchewan. But if I don't, I'll report back here after I build the weather station. Thanks again.
