GENERAL USE :

1) You just need to connect to Arduino interrupt pin 2, and can measure the number of PWM pulse/interrupt per unit of time. The water flow would be directly proportional to the number of measured pulses. 2)Water flow sensor can be used to measure the flow of liquids, i.e. the consumption of liquids in industrial or domestic usage. For example you can make a robotic cocktail dispensing machine, and can use this sensors to accurately measure components like Soda, Water, etc. Water flow sensor consists of a plastic valve body, a water rotor, and a hall-effect sensor. When water flows through the rotor, rotor rolls. Its speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse Signal.

Arduino Example Sketch Below:

/*

YF-S201 Hall Effect Water Flow Meter / Sensor

http://www.hobbytronics.co.uk/yf-s201-water-flow-m...

Read Water Flow Meter and output reading in litres/hour

*/

volatile int flow_frequency; // Measures flow meter pulses

unsigned int l_hour; // Calculated litres/hour

unsigned char flowmeter = 2; // Flow Meter Pin number

unsigned long currentTime;

unsigned long cloopTime;

void flow () // Interruot function

{

flow_frequency++;

}

void setup()

{

pinMode(flowmeter, INPUT);

Serial.begin(9600);

attachInterrupt(0, flow, RISING); // Setup Interrupt

// see http://arduino.cc/en/Reference/attachInterrupt

sei(); // Enable interrupts

currentTime = millis();

cloopTime = currentTime;

}

void loop ()

{

currentTime = millis();

// Every second, calculate and print litres/hour

if(currentTime >= (cloopTime + 1000))

{

cloopTime = currentTime; // Updates cloopTime

// Pulse frequency (Hz) = 7.5Q, Q is flow rate in L/min. (Results in +/- 3% range)

l_hour = (flow_frequency * 60 / 7.5); // (Pulse frequency x 60 min) / 7.5Q = flow rate in L/hour

flow_frequency = 0; // Reset Counter

Serial.print(l_hour, DEC); // Print litres/hour

Serial.println(" L/hour");

}
