Weather Instrument With Anemometer and Wind Vane Made Up of Four Printed Parts A 5mm Screw Attached to the Bottom Part A 608zz Bearing Fixed Between Rotor and Cups with 3mm Screws A 9mm Magnet Inserted on the Rotor The Wind Speed is Calculated with a Reed Switch For the Wind Vane, a Continuous Single Turn Potentiometer is Used Use With Arduino as Described Here: http://cactus.io/hookups/weather/anemometer/davis/hookup-arduino-to-davis-anemometer-software Update: The Electronic Components Used Include: One Potentiometer for the Wind Vane, Such As This Example: http://www.conrad.com/ce/en/product/1055299/Single-turn-rotary-pot-Mono-1-W-1-k-Bourns-1-pcs One Reed Switch Triggered by a Magnet Attached to the Rotor An Arduino Mini to Calculate Wind Speed and Direction: https://www.arduino.cc/en/Main/arduinoBoardProMini I Managed to Hook Up the Wires to Arduino Using Online Information The Arduino Code is from This Source: http://cactus.io/hookups/weather/anemometer/davis/hookup-arduino-to-davis-anemometer-wind-speed An M5 Hexagonal Screw Attached and Secured on the Bottom Part Will Be the Rotor Axis Four M3 40mm Screws to Join the Main Two Parts (Top & Bottom) and Three M3 20mm Screws to Fix Cups on the Rotor This Project is On Hold Until Spring But I Can Share Some Results from Testing It: My Potentiometer is Hard to Turn by Hand and Not So Effective for Wind Direction The Rotor is Easy to Turn Even on Low Winds and Readings are Accurate A Four-Wire Connection for 5V and Serial Reading is Attached to the Arduino and Cannot Be Reprogrammed While the Case is Closed I Didn't Test It Outside During Winter to Calibrate It UPDATE 2: Added New Anemometer Cups with Support for Two Bearings: http://www.thingiverse.com/download:3548001 First Run: https://www.youtube.com/watch?v=S4hPwpiY1XQ
