  • DIY Anemometer: Wind Speed Sensor Device 9 months ago

    I did not calculate exact wind speed. My requirement was limited to quantifying into moderate wind and high wind. Since the motor I used has a strong magnet, the resistance caused no movement at low wind, at moderate wind I get 0-1V and 1v+ is high wind in my setup.

    Calculating exact wind speed will be a more complex calculation since there are gears involved and the size of gear and teeth density on the edge of the gears (and the number of such gears, gear ratios) I use between the Wind Spoon shaft and the motor shaft will determine at what wind speed I generate how much current. Thus a pre-calculation may not be helpful to anyone trying this project.

    As @abhinav suggested, the easiest would be to connect a Voltmeter to the motor output and take this device out for a ride. Map V to MPH in your car/bike :-)

    Well, I used Induino-R3 which has an LED on-board (I used that) but Photodiode on the board had problems so I used an external diode. The schematics I shared is of an Arduino board which reflects the circuitry and components. It is applicable to all boards built on Arduino. If you are using an Induino, you may consider using on-board components.

    Do you mean, If you keep signal high for 3 sec, only then you get something on receiver or you mean that dotLength has to be 3 sec (3000ms)? Message me details directly.
