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.
Arduino water flow sensor code.
There is a small calculation in the code which i will explain in the further sections.
This type of flow sensor is designed to measure the volume of liquid traveling past a given point a great way to keep tabs on how much water your drip irrigation system is using or any other project were the flow of liquid needs to be tracked.
In this project we will interface yfs201 hall effect water flow sensor with arduino for measuring flow rate and volume of water or any other liquid this is a very wonderful project that can be used in industry or at home or at water flow measurement application in water tap tunnel river etc.
Anyone can do it.
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.
For this purpose using interrupts is a best choice.
The explanation of the code is as follows.
Communication started with 9600 baud void loop int sensor analogread a1.
Wrote serial port let s prepare the circuit.
Lets begin and make circuit i will explain the code and circuit later.
Arduino have to count the number of pulses outputted by the water flow sensor.
The code uses an external interrupt on the arduino s digital pin 2.
Note that the water flow sensor is not a power hungry type.
The complete water flow sensor arduino code is given at the bottom of the page.
How to use water flow sensor arduino tutorial.
We are using the header file of the lcd which eases our interfacing the lcd with arduino and the pins 12 11 5 4 3 9 are allotted for data transfer between lcd and arduino.
Upload the flow meter code to your arduino.
In this tutorial we will be hooking up a flow sensor to an arduino uno to measure liquid flow.
When the arduino detects the pulse it immediately triggers the pulsecounter function.
In order to obtain this there is a small calculation.
This is used to read the pulses coming from the flow meter.
The water sensor has 3 output pins.
The code for the arduino water flow sensor interface is given below.
Water flow sensor for flow rate volume measurement using arduino code along with.
The sensor s output pin is connected to pin 2 of.
S this output goes to any analog signal on arduino.
It draws a maximum of 15 20ma at 5v dc input.
This project is very basic.
Incoming analog signal read and appointed sensor serial println sensor.
In this project use the yf s201 1 2 inch water flow sensor to measure the water flow rate l min and display it on an lcd.
