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