The sensor s output pin is connected to pin 2 of.
Arduino water flow sensor code.
The water sensor has 3 output pins.
Uploading the flow meter code to the arduino and measuring water flow rate.
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.
The explanation of the code is as follows.
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.
There is a small calculation in the code which i will explain in the further sections.
When the water flows through the rotor rotor rolls and the speed.
S this output goes to any analog signal on arduino.
Lets begin and make circuit i will explain the code and circuit later.
Anyone can do it.
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.
The complete water flow sensor arduino code is given at the bottom of the page.
The code for the arduino water flow sensor interface is given below.
When the arduino detects the pulse it immediately triggers the pulsecounter function.
Upload the flow meter code to your arduino.
The code uses an external interrupt on the arduino s digital pin 2.
This is used to read the pulses coming from the flow meter.
In order to obtain this there is a small calculation.
Water flow sensor for flow rate volume measurement using arduino code along with.
For this purpose using interrupts is a best choice.
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.
This project is very basic.
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.
Note that the water flow sensor is not a power hungry type.
Arduino have to count the number of pulses outputted by the water flow sensor.
Communication started with 9600 baud void loop int sensor analogread a1.
Wrote serial port let s prepare the circuit.
It draws a maximum of 15 20ma at 5v dc input.
How to use water flow sensor arduino tutorial.
The output of the project is to display the quantity of water flowing through the sensor in litres per hour as shown below.
