Anemometer Wind Speed Sensor

Features:

• Anemometer
• Analog Output from 0 to 4V DC
• Measure wind speed
• Max wind speed: 124 mph
• Max Voltage (at max wind speed): does not exceed 4V
• Nominal wind speed: less than 64mph (0 to 2V output)
• As speed increases, voltage increases
• Number of bowls: 3
• Bowl Type: Spherical
• Bowl Diameter: 1.5 inch
• Bowl Pitch: 120 degrees
• Diameter of Anemometer: 5.35 inches
• Height: 2.6 inches
• 46mm diameter base with 3 mounting holes 31mm apart from eachother (18mm 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 4V 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)*50=KM/H (wind speed)
  • Voltage (V)*14=M/S (wind speed)
  • If the current output signal voltage is 0.5V, it indicates that the current wind speed is about 25KM/H or about 7M/S
  • For threshold detection you can just look up the voltage on the graph provided and compare if the sensor's voltage is above the voltage for that wind speed.
• Mount in a horizontal position
