If the output valve of the pipe is closed the output of the water flow sensor is zero no pulses.
Water flow sensor arduino working.
There will be no interrupt signal seen at the pin 2 of the arduino and the count of the flow frequency will be zero.
These sensors can be easily interfaced with microcontrollers like arduino.
Arduino water flow sensor working.
Specifications of 1 2 inch water flow sensor yf s201 model.
How to use water flow sensor arduino tutorial.
Hall sensor has 3 pins two pins are for power and one pin is for output.
Flow meter working principle.
When the water flows through the rotor rotor rolls and the speed.
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.
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.
In our project we connected the water flow sensor to a pipe.
In water flow meter a small fan wings like rotor is placed in way of fluid.
Shaft of this structure has magnetic link with hall s effect sensor.
Yf s201 1 2 inch water flow sensor has only three wires and it can be easily interfaced between any microcontroller and arduino board.
Working of yfs201 hall effect water flow sensor.
The water flow sensor for flow rate volume measurement using arduino works on the principle of the hall effect.
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.
Connecting the water flow sensor to arduino requires minimal interconnection.
The sensor s output pin is connected with arduino board pin 2.
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.
Water flow sensor as the name suggests is a device to measure the flow of water.
The water flow sensor used in this project is shown in the image below.
Arduino water flow sensor working.
There will be no interrupt signal seen at the pin 2 of the arduino and the count of the flow frequency will be zero.
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.
The water flow sensor can be used with hot waters cold waters warm waters clean water and dirty water also.
It requires only 5v vcc and gives pulse output the sensor needs to be tightly fitted between water pipeline.
