The water flow sensor for flow rate volume measurement using arduino works on the principle of the hall effect.
Water flow sensor arduino working.
Yf s201 1 2 inch water flow sensor has only three wires and it can be easily interfaced between any microcontroller and arduino board.
Connecting the water flow sensor to arduino requires minimal interconnection.
In our project we connected the water flow sensor to a pipe.
If the output valve of the pipe is closed the output of the water flow sensor is zero no pulses.
Arduino water flow sensor working.
Flow meter working principle.
Working of yfs201 hall effect water flow sensor.
Water flow sensor as the name suggests is a device to measure the flow of water.
Water flow sensing in water metering systems.
A brief note on water flow sensor.
The water flow sensor can be used with hot waters cold waters warm waters clean water and dirty water also.
Hall sensor has 3 pins two pins are for power and one pin is for output.
There will be no interrupt signal seen at the pin 2 of the arduino and the count of the flow frequency will be zero.
It requires only 5v vcc and gives pulse output the sensor needs to be tightly fitted between water pipeline.
According to the hall effect a voltage difference is induced in a conductor transverse to the electric current and the magnetic field perpendicular to it.
In water flow meter a small fan wings like rotor is placed in way of fluid.
These sensors are available in different diameters with different flow rate ranges.
Just as shown in the schematic diagram the flow sensor is connected with arduino board using jumper wires.
If the output valve of the pipe is closed the output of the water flow sensor is zero no pulses.
The sensor s output pin is connected with arduino board pin 2.
Shaft of this structure has magnetic link with hall s effect sensor.
The water flow sensor used in this project is shown in the image below.
There will be no interrupt signal seen at the pin 2 of the arduino and the count of the flow frequency will be zero.
Circuit diagram of water flow meter working of water flow meter using arduino and yf s201.
In this project i will talk a little bit water flow sensors how a water flow sensor works and how to interface a simple water flow sensor with arduino.
When the water flows through the rotor rotor rolls and the speed.
In this tutorial you will learn how to use one water flow sensor with an arduino board the water flow sensor consists of a plastic valve body a water rotor and a hall effect sensor.
Connect the vcc red and gnd black wires of the water flow sensor to the 5v and gnd of arduino and link pulse output yellow wire of the water flow sensor to arduino s digital pin 2.
In our project we connected the water flow sensor to a pipe.
