WATER FLOW SENSOR

                                                    Water flow sensor is used to sense the volumetric measure of the water. 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. We can interface water flow sensor with Arduino to measure the volume of water present.

Application:

• To determine the volume of water used  in a House pipes.
• To determine the volume of petroleum  transferred in oil and gas industries.

Sample Project With Arduino:

                                 In this we going to measure the volume of water using the water flow sensor.

Materials required:

• Arduino UNO
• Water flow sensor
• Jumper wires

Circuit:

Code:

const byte interruptPin = 2;

uint32_t pulse;

uint32_t  Litre;

void setup() {

  Serial.begin(9600);

  pulse = 0;

  Litre = 0;

  pinMode(interruptPin, INPUT_PULLUP);

  attachInterrupt(digitalPinToInterrupt(interruptPin), cal, FALLING);

}

void loop() {

}

void cal() {

  pulse += 1;

  Litre = ( pulse  * 4.5  / 10 );

  Serial.print(Litre, DEC);

  Serial.println(" Milli Liter");

}
