Anemometer Wind Speed Sensor

This anemometer measures wind speed! As it rotates, it drives a small DC generatorwhich produces DC voltage. The voltage output increases from 0 to 2V.

  • Anemometer
  • Analog Output from 0 to 2V DC
  • Measure wind speed
  • Max wind speed: 124 mph
  • Normal wind speed: less than 64mph (0 to 1V output)
  • As speed increases, voltage increases
  • Number of bowls: 3
  • Bowl Type: Spherical
  • Bowl Diameter: 2.36 inch
  • Bowl Pitch: 120 degrees
  • Diameter of Anemometer: 8.7 inches
  • Height: 3.54 inches
  • 58mm diameter base with 3 mounting holes 41mm apart from eachother (25mm from center)
  • Base Screw Hole Mount Size: M6
  • Cable Length: approx 9.8ft
  • Suitable for DIY Weather Stations, Raspberry Pi and Arduino Weather Station projects and other projects where a microcontroller is used to measure windspeed.
  • The sensor is self-generating, no additional power supply necessary. When there is wind rotation, it generates the voltage signal.
  • Pinout:
    • Red: Analog Signal Out - values from 0 to 2V DC (connect to microcontroller analog input pin)
    • Black: Ground - Ground 0V (connect to microcontroller GND)
  • Formulas for calculating wind speed from signal output voltage:
    • Voltage (V)*90=KM/H (wind speed)
    • Voltage (V)*25=M/S (wind speed)
  • Mount in a horizontal position
Is this anemometer waterproof?
Yes, it can handle rain and snowy weather conditions as long as it is not soaked / submerged.

Can it be hooked up to power with 120v or is there one I\'m confused about how it operates any feedback would be appreciated.
No power input is needed. As it rotates, it drives a small DC generator which produces DC voltage. The voltage output increases from 0 to 1.2V depending on the wind speed.
