Anemometer for Raspberry Pi

thingiverse

Here's an anemometer for your Raspberry Pi that's easy to build and requires minimal materials. You can use either a Hall effect or Reed Switch sensor, which you'll hot glue onto the side of the main body through its opening. Next, attach a neodymium magnet to the threaded rod using more hot glue. To assemble this project, you'll need: * 2 x 608z bearings * 5 x M8 nuts * 3 x washers * A threaded rod The main body of the anemometer can be screwed down securely. This feature is particularly useful if you want to attach it to the roof of your allotment shed. To create the cups, simply push them into the center ring. You have two options for attaching them: either super glue or hot glue will work, but if you're feeling ambitious, you could also try PLA welding them in place. As for the RPM, I've found that it can get quite high when tested with a drill attached to the threaded rod. In fact, one of my cups flew out at an incredibly fast speed! Don't worry, though - I'll be sharing a step-by-step build guide on Instructables soon.
