DoubleWaterMeterPulseSensor on 1 Node v2.0



  • Please help me to compile this scetch for hot (HW_) and cold (CW_) water meter on 1 arduino.
    I use the original code from Water Meter Pulse Sensor, but I dont know how to fix "PULSE_FACTOR" - error

    @tjay4x4 on a mobile device now so I can't verify but I think changing

    define HW_PULSE_FACTOR 1000                       // Nummber of blinks per m3 of your meter (One rotation/liter)
    #define CW_PULSE_FACTOR 1000                       // Nummber of blinks per m3 of your meter (One rotation/liter)
    

    to

    define PULSE_FACTOR 1000                       // Number of blinks per m3 of your meter (One rotation/liter)
    

    will be sufficient.



  • @mfalkvidd Thank you for reply!
    I'm trying this before, when I change it to

    define PULSE_FACTOR 1000
    
    
    

    I get this red line in the code;

     attachInterrupt(digitalPinToInterrupt(HW_DIGITAL_INPUT_SENSOR), onPulse, FALLING);
     attachInterrupt(digitalPinToInterrupt(CW_DIGITAL_INPUT_SENSOR), onPulse, FALLING);
    
    C:\Users\Барков\Desktop\_2WaterMeterPulseSensor\_2WaterMeterPulseSensor.ino: In function 'void setup()':
    
    _2WaterMeterPulseSensor:105: error: 'onPulse' was not declared in this scope
    
    exit status 1
    'onPulse' was not declared in this scope
    ```
