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