Custom Made Anemometer with Arduino & Oled Display

As an Arduino enthusiast, I found making projects with Arduino to be most fun for me. There is so much to learn from them as a maker and an engineer. So, here are my Arduino project related to wind measurement, crafted in 2 days. The project is calculating real time wind speed on OLED Display.

What is that sensor in the propeller?? Please reply.

How did you do the anemometer calibration? How many turns for 1 km, or is there a formula?

[@JohnWeland]

I've never seen one built with 3 triggers (the 3 magnets) but I would wager the code looks something like
rotations per second = float(rotation/10) / 3 [since there are three magnets]
windspeed = float (rotation per second, * vane_circumference * variance) [variance will be somewhere between 1.2 and 3, its a little helper to make up for the energy loss of the wind movign the anemometer]
windspeed is m/s, so windspeed * 2.237 for mph or (windspeed * 18)/5 for kph.
This is me just taking a stab at it blindly having not built and programmed my own yet.

Here is the complete code I made up quickly, if you use it let me know how you go....it should be the same as this video using two photo interrupters, a 2in disk with 10 holes and an oled display.
#include
#include
#include
#define SCREEN_WIDTH 128
#define SCREEN_HEIGHT 64
#define OLED_RESET 4
Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);
const int sensorPin1 = 2; // Pin for the first photo interrupter
const int sensorPin2 = 3; // Pin for the second photo interrupter
volatile unsigned long lastInterruptTime1 = 0; // Time of the last interrupt for sensor 1
volatile unsigned long lastInterruptTime2 = 0; // Time of the last interrupt for sensor 2
volatile unsigned long revolutions = 0; // Number of full disk revolutions
volatile float windSpeed = 0.0; // Calculated wind speed
const float circumference = 12.56; // Circumference of the 2-inch disk in inches
const int holes = 10; // Number of holes in the disk
void setup() {
pinMode(sensorPin1, INPUT_PULLUP);
pinMode(sensorPin2, INPUT_PULLUP);
attachInterrupt(digitalPinToInterrupt(sensorPin1), sensor1ISR, FALLING);
attachInterrupt(digitalPinToInterrupt(sensorPin2), sensor2ISR, FALLING);
display.begin(SSD1306_SWITCHCAPVCC, 0x3C);
display.display();
delay(2000);
display.clearDisplay();
display.setTextColor(WHITE);
display.setTextSize(2);
}
void loop() {
unsigned long timeElapsed1 = micros() - lastInterruptTime1;
unsigned long timeElapsed2 = micros() - lastInterruptTime2;
if (timeElapsed1 > 1000000 || timeElapsed2 > 1000000) {
// No new interrupts, wind speed is zero
windSpeed = 0.0;
} else {
// Calculate wind speed based on the time between interrupts
float timeInSeconds = (timeElapsed1 + timeElapsed2) / 1000000.0;
float revolutionsPerSecond = (float)revolutions / timeInSeconds;
windSpeed = (revolutionsPerSecond * circumference) / holes;
revolutions = 0; // Reset the revolution count
}
display.clearDisplay();
display.setCursor(0, 0);
display.print("Wind Speed:");
display.setCursor(0, 20);
display.setTextSize(3);
display.print(windSpeed);
display.setTextSize(1);
display.print(" in/s");
display.display();
delay(1000); // Delay between measurements
}
void sensor1ISR() {
if (micros() - lastInterruptTime1 > 1000) {
// Ignore interrupts that are too close together (noise)
revolutions++;
lastInterruptTime1 = micros();
}
}
void sensor2ISR() {
if (micros() - lastInterruptTime2 > 1000) {
// Ignore interrupts that are too close together (noise)
revolutions++;
lastInterruptTime2 = micros();
}
}

[@andreasioannides3644]

formula for sure ,,

[@JohnBobRoger]

Ok did I miss it? How does it work and communicate? RS-422, or RS-485, or 4 -20mA Current loop?

[@andreasioannides3644]

is a custom project i can make it in any communicate needs,

[@ivandjones]

Could you tell us about your CNC?
