G 1/2 Water Flow Sensor

Postby alhafidzashraf » Fri Nov 13, 2015 1:07 pm

hello,

im using arduino Yun and the water flow sensor YF-S201 and using the code by Seeedstudio.


volatile int NbTopsFan; //measuring the rising edges of the signal
int Calc;
int hallsensor = 2; //The pin location of the sensor

void rpm () //This is the function that the interupt calls
{
NbTopsFan++; //This function measures the rising and falling edge of the hall effect sensors signal
}
// The setup() method runs once, when the sketch starts
void setup() //
{
pinMode(hallsensor, INPUT); //initializes digital pin 2 as an input
Serial.begin(9600); //This is the setup function where the serial port is initialised,
attachInterrupt(0, rpm, RISING); //and the interrupt is attached
}
// the loop() method runs over and over again,
// as long as the Arduino has power
void loop ()
{
NbTopsFan = 0; //Set NbTops to 0 ready for calculations
sei(); //Enables interrupts
delay (1000); //Wait 1 second
cli(); //Disable interrupts
Calc = (NbTopsFan * 60 / 7.5); //(Pulse frequency x 60) / 7.5Q, = flow rate in L/hour
Serial.print (Calc, DEC); //Prints the number calculated above
Serial.print (" L/hour\r\n"); //Prints "L/hour" and returns a new line
}

but still the result still 0 L/hour. is it something wrong somewhere in this code or this sensor is broken? pls help.

Thank you very much! :D :D :D :D :D

I've tried but still doesn't work nothing changes still the reading 0.
btw thanks.
