Tobiyouth/WaterFlow

Arduino water Flow Rate, Water Volume

Description

Arduino library for Flow Sensor.

Flowrate Formula

The SensorConstant is different for different models.

$$Q = Frequency / SensorConstant$$

Q = Flowrate (Liter/minute)

Usages

initialization

#include <WaterFlow.h>

//SensorConstant is 65
WaterFlow waterFlow(PIN2, 65);

Sensor begin

param userFunc

void count() {
  waterFlow.pulseCount();
}

//The begin function must be called from the setup function
void setup() {
  waterFlow.begin(count);
}

Sensor Read

//The read function must be called from the loop function
void loop() {
  waterFlow.read();
}

Get Flowrate (L/m)

return Flowrate (L/m)

float getFlowRateOfMinute() 

Get Flowrate (mL/s)

return Flowrate (mL/s)

int getFlowRateOfSecond() 

Get Total Volume (mL)

return Volume (mL)

long getVolume()

Clear Total Volume

void clearVolume()

Determine if it is flowing

return true or false

bool isFlowing()

Start and stop the listener

void setListeners(void (*start)(void), void (*stop)(void));

Example

#include "WaterFlow.h"

WaterFlow waterFlow(PIN2, 65);

unsigned long beforeTime;

void count() {
  waterFlow.pulseCount();
}


//Make a sound when starting or stopping.
void buzz(){
   tone(3, 800, 500);
}

void setup() {
  waterFlow.begin(count);
  waterFlow.setListeners(buzz, buzz);

  Serial.begin(9600);
}

void loop() {
  waterFlow.read();

  if ((millis() - beforeTime) >= 1000){
    beforeTime = millis();

    if(!waterFlow.isFlowing()){
      waterFlow.clearVolume();
      return;
    }

    Serial.print(waterFlow.getFlowRateOfMinute());
    Serial.print(" L/m   ");

    Serial.print(waterFlow.getFlowRateOfSecond());
    Serial.print(" mL/s   ");

    Serial.print(waterFlow.getVolume());
    Serial.println(" mL");
  }
}
