Anemometer V1 for Arduino

Anemometer V1 for Arduino

Anemometer V2 is available here: v2 printable
 

Material: 

• 3 x 4x2mm Neodymium magnet
• A3144 hall effect sensor
• 10K resistor
• Arduino Nano

It uses 3 magnets that are inserted/glued inside the head in the hole (I had to use 3 to keep everything balanced).

Inside the body (base tube) is inserted an A3144 hall effect sensor and a 10k resistor, all plugged to an Arduino Nano.

I use a nail inserted in the main body to let the head rotate freely.
