Wind speed sensor node

[JohanRC]

Yesterday I found some example code on the Domoticz forum.

With some modifications I get numbers in wind :smiley:

As below my current sketch that sends values, I will modify it untill it is what I like and will post it here.

#include <SPI.h>
#include <MySensor.h>  

#define CHILD_ID_WIND 20

#define LED_PIN 8

#define ID_WIND 170

#define WIND_SENSOR_ANALOG_PIN 1

MySensor gw;
unsigned int val_wspeed;
unsigned int val_wgust;
unsigned int val_wdirection;


unsigned int last_wspeed;
unsigned int last_wgust;
unsigned int last_wdirection;


boolean metric = true; 

unsigned long currentTime;
unsigned long SEND_FREQUENCY = 10000;
unsigned long lastSend;

MyMessage msgWSpeed(CHILD_ID_WIND, V_WIND);
MyMessage msgWGust(CHILD_ID_WIND, V_GUST);
MyMessage msgWDirection(CHILD_ID_WIND, V_DIRECTION);

//Setup routine
void setup()  
{ 
  
    // Initialize library and add callback for incoming messages
  gw.begin();

  // Send the Sketch Version Information to the Gateway
  gw.sendSketchInfo("Windsensor", "0.1");

  // Register all sensors to gw (they will be created as child devices)
  gw.present(CHILD_ID_WIND, S_WIND);

  metric = gw.getConfig().isMetric;
  lastSend = 0;

  pinMode(LED_PIN, OUTPUT); 
  digitalWrite(LED_PIN,1);
}

//Main loop
void loop()      
{  
  gw.process();
 
  currentTime = millis();
  
  unsigned int val_wspeed = (analogRead(WIND_SENSOR_ANALOG_PIN))/31.605; 
  
    if(last_wspeed != val_wspeed)
    { 
       last_wspeed = val_wspeed;
       gw.send(msgWSpeed.set(val_wspeed, 1));
       Serial.print("WS: ");
       Serial.println(val_wspeed);
    }
    
    unsigned int val_wgust = (analogRead(WIND_SENSOR_ANALOG_PIN))/31.605; 
    if(last_wgust != val_wgust)
    { 
       last_wgust = val_wgust;
       gw.send(msgWGust.set(val_wgust, 1));
       Serial.print("WG: ");
       Serial.println(val_wgust);
    }
    
    unsigned int val_wdirection = (analogRead(WIND_SENSOR_ANALOG_PIN))/2.842; 
    if(last_wdirection != val_wdirection)
    { 
       last_wdirection = val_wdirection;
       gw.send(msgWDirection.set(val_wdirection, 1));
       Serial.print("WD: ");
       Serial.println(val_wdirection);
    }
}
