Introduction

This experiment shows how to measure the wind direction using an anemometer or wind vane connected to an Arduino.

• Arduino
• Jumper Wires

Circuit Setup

1. Connect the wind vane sensor’s output pin to an analog input pin on the Arduino.
2. Ensure the power and ground pins are connected properly to the 5V and GND pins of the Arduino.

The wind vane sensor detects the direction of the wind and sends a signal to the Arduino, which processes the data and calculates the wind direction.

Code for Wind Direction Measurement

Upload the following code to your Arduino to measure wind direction:

const int windPin = A0;

void setup() {
  Serial.begin(9600);
}

void loop() {
  int windDirection = analogRead(windPin);
  Serial.print("Wind Direction: ");
  Serial.println(windDirection);
  delay(1000);
}
            

Explanation

The wind vane sensor detects the angle of the wind, and the Arduino reads the signal to calculate the direction of the wind.

Troubleshooting

• Ensure that the sensor is placed in a location where wind direction can be clearly detected.
• Check wiring connections if data is not being received by the Arduino.
