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.
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!
