What is wind speed sensor?
Wind speed sensor is a physical device used to measure wind speed. The wind generated by the airflow drives the top three wind cups to rotate, and the central axis drives the internal sensing element to generate an output signal, which can be used to calculate the wind speed.
How does Arduino measure wind speed?
Once you upload the Arduino Anemometer code to the Arduino Board, the OLED Display will start displaying the wind speed. When the anemometer cup is stable the OLED will show speed around 0.1m/s to 0.3m/s. The speed will vary or increase when the sensor is taken in a windy region.
How do I monitor wind speed?
Wind speed is measured with an anemometer. Most anemometers have four horizontal shafts arranged like the spokes of a wheel. The end of each shaft is cup-shaped. The wind pushes the concave side of the cup more than the convex side, so the anemometer spins in the wind.
How do you test a wind speed sensor?
Connect the brown wire from the cup anemometer to the ground terminal on the digital multimeter (typically labeled COM) and the white wire from the cup anemometer to the resistance terminal on the digital multimeter (typically labeled Ω). Check that the resistance reading on the digital multimeter is 650 Ω ± 50 Ω.
How do you calculate wind speed with an anemometer?
Take your anemometer outside and measure the wind speed. To do so, count the number of times the cup with the red mark passes in front of you in 30 seconds. Multiply by two to get revolutions/rotations per minute (rpm).
How do you measure wind speed?
Calculate a miles per hour wind speed in feet per hour, then divide by the number of feet in a knot. For the example wind speed of 100 mph, do as follows: 100 mph x 5,280 feet = 528,000 feet per hour; 528,000 feet per hour/6,080 feet = 86.8 knots.
Where do you mount an anemometer?
A roof-top works the best. Try to place the anemometer as high as is convenient. Try to make the anemometer the highest object around. 7 feet or more above the surrounding obstructions is best.
Where do you place a wind sensor?
Wind Sensors The wind sensor should be the highest item in the area. Position the wind sensor at least 6 feet above the surface to which it is being mounted. Wind sensors with directional vanes should be positioned according to the N, S, E, W directions on the sensor near the vane.
