sonda PH



  • Hello, I'm sorry for my Anglish.
    I was looking for a connection of soda PH to domoticz. I found one project but it is old and it does not work. There is somebody able to do it, I'm sure it will not be useful to one.

    #include <Average.h>
    Average<float> sredniaPH(100); //średnia ze 100 pomiarów
    void setup()
    {
    Serial.begin(9600);
    }
    void loop()
    {
    int Volty = analogRead(A7);
    float V =(float) Volty * 5.0 / 1024.0;
    float peha =(float) V*3.5;
    sredniaPH.push(peha);
    sredniaPH.mean();
    float pH =((float) sredniaPH.mean());
    Serial.println(pH);

      delay(1000)
    

    }



  • Hi, @szybki946 !
    Code in your post is working or not?
    If yes - you want to someone modify it, so it will send your pH to domoticz from MySensors node?
    If yes - if you use nrf24l01+ radio - maybe you want this code:

    #include <Average.h>
    
    #define MY_NODE_ID 100 //set node fixed id
    #define MY_BAUD_RATE 9600 //set serial baud rate
    #define MY_RADIO_RF24 //if you use nrf24l01+
    
    #include <MySensors.h>  
    
    #define PH_CHILD_ID 0
    
    MyMessage ph_msg(PH_CHILD_ID, V_PH);
    
    Average<float> sredniaPH(100); //średnia ze 100 pomiarów
    
    void presentation() {
      sendSketchInfo("PH_meter", "1.0");  // Send the sketch version information to the gateway and Controller
    
      present(PH_CHILD_ID, S_WATER_QUALITY, "average_ph");
    }
    
    void setup()  
    { 
      //Serial.begin(9600); //don't need it because of #define MY_BAUD_RATE 9600
    }
    
    void loop()     
    {     
      int Volty = analogRead(A7);
      float V =(float) Volty * 5.0 / 1024.0;
      float peha =(float) V*3.5;
      sredniaPH.push(peha);
      sredniaPH.mean();
      float pH =((float) sredniaPH.mean());
      Serial.println(pH);
    
      send(ph_msg.set(pH, 2)); //2 = number of digits after comma
      wait(1000); //in mysensors do not use delay - use wait() or sleep()
    }
    
    

    (change IDs, texts and numbers of digits after comma as you want)
