pluviometer

This is a pluviometer wich detects the water collect movement by using a small neodymium magnet and a hall effect sensor. Then it is posible to collect the pulses with an arduino microcontroller.
The pluviometer is made of ABS, and it is recommended to use acetone after printing in order to get a smooth Surface.
you will need two small ball bearings (3 * 8 * 4mm) like:

The hall effect sensor is a KY-003:
