Anemometer V2 for Arduino

Anemometer V2 for Arduino

Anemometer V1 available here: v1 printable

New Features:

• Lighter - easier to spin, less mass - less momentum.
• Integrate only one imbedded magnet.
• Lower center of gravity - more stable.

Material: 

• 1 x 10x1.8mm Neodymium magnet
• A3144 hall effect sensor
• 10K resistor
• Arduino Nano

It uses 1 magnets that are inserted inside the head during the print (add a pause at layer 47 for a 0.2mm layer height - if you need information about imbedded magnet into a 3d print, post a comment or send me a pm).

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 pop rivet (4mm head - 2mm pin), sharpen and inserted in the main body to let the head rotate freely.
