Anemometer

An anemometer is a machine used to find out wind speed. Check the DIY page of DIY anemometer. Now, its shape is ALMOST like a compass—it has 4 sides. But, it can be heavy, so no magnetic field here! You can buy portable anemometers, which are about, let me see, ~3 lbs? IDK, but check it out for yourself—measure each day, so you don’t have to watch your weather station!
