The result of my friend's extraordinary work, making a homemade local weather station to get weather predictions around you is very important, and I can also see in some of the graphs that you show there are some data clues, and hopefully your work can be maximized.
My question is, is this tool resistant to rain and lightning my friend, because I see this tool installed freely without even a cover.
Sure seems like a cool gadget.. yes it is meant to be out in the open. The rain sensor needs water to hit it to read it..
As for a lighting strike.. lol hopefully it does not get struck.. Would probably destroy it.
