How to measure wind speed using Arduino?
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 you make an electronic anemometer?
So, to make the anemometer all we need to do is put the magnetic switch from the speedometer next to the magnet on the wind cups, and “voila”. The main work in this project is to construct a mounting block which will hold the wind cups and switch in the proper positions, and allow the wind cups to rotate freely.
How anemometer is used to measure?
The stronger the wind blows, the faster the wheel rotates. The anemometer counts the number of rotations, which is used to calculate wind speed. An anemometer is an instrument that measures wind speed and wind pressure. Anemometers are important tools for meteorologists, who study weather patterns.

How does an electronic anemometer work?
It uses an electrically animated hot piece of wire similar to the thread in an out-of-date light bulb past which the wind blows. As the wire chills, its electrical confrontation changes can be measured to figure out the amount of cooling and the wind speed.
How do you use a digital anemometer step by step?
Reading a Digital Anemometer. Hold the device high in the air. Once you have selected the measurement option, you are ready to calculate the wind speed. Simply hold the device in the air.
How does a homemade anemometer measure wind speed?
Use a red marker or red paint and put a large X on one of the cups. 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).
What is digital anemometer?
Digital Anemometer allows measuring atmospheric effects, namely wind velocity, temperature, and humidity for better data analysis. It also possesses various features such as Beaufort scale, switch between Celsius and Fahrenheit, switch between metric and imperial system, or the battery status indicator.
What scale is wind speed?
The Beaufort Scale
The Beaufort Scale is still used today to describe the speed of wind at sea and the effect of wind on the surface of the water. Wind speed is measured in knots, with one knot equal to one nautical mile per hour.
How do you make a weather detector?
Materials
- Two alcohol-filled air thermometers (they must read exactly the same temperature when placed side by side out of direct sunlight)
- Clear packing tape.
- Cotton shoelace (the hollow type)
- One- or two-liter bottle (label removed)
- Water (distilled is best but tap will do)
- Thread.
- Awl.
- Relative humidity chart.
