Crowtail- G1/2" Water Flow Sensor
Contents
Description
Crowtail G1/2 "water flow sensor isconsists of magnetic core, rotating impeller, external casing and sensor and a hall-effect sensor. When water flows through the rotor, rotor rolls, it activates the magnetic core to trigger switch action speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse signals, users can get the flow speed via detecting the pulse. It is suitable to detect flow in water dispenser or coffee machine.There are also lots of other water flow sensors in other diameters for your choice.

Usage
Here is an example showing how to turn on the Crowtail- G1/2" Water Flow Sensor.
1. Plug it onto the Digital port 2 of Crowtail - Base Shield using a Crowtail cable.
2.Plug the Crowtail - Base Shield onto Arduino.
3. Connect Arduino to PC by using a USB cable.
4.Let the water flow connect to a water pipe.
5. Copy and paste code below to a new Arduino sketch, and upload it to your Arduino.
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) / 73.Q, = 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 }
6.When you upload the code complete,you can measure the water flow rate and see the result via the serial port debug window
