Arduino Water Flow Sensor Code

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.

Arduino water flow sensor code.

Anyone can do it. 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. 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. The complete water flow sensor arduino code is given at the bottom of the page.

The water sensor has 3 output pins. In order to obtain this there is a small calculation. 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. 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. Communication started with 9600 baud void loop int sensor analogread a1. 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. Wrote serial port let s prepare the circuit.

The sensor s output pin is connected to pin 2 of. Upload the flow meter code to your arduino. Water flow sensor for flow rate volume measurement using arduino code along with. Arduino have to count the number of pulses outputted by the water flow sensor.

The code for the arduino water flow sensor interface is given below. The output of the project is to display the quantity of water flowing through the sensor in litres per hour as shown below. When the arduino detects the pulse it immediately triggers the pulsecounter function. It draws a maximum of 15 20ma at 5v dc input.

This is used to read the pulses coming from the flow meter. Lets begin and make circuit i will explain the code and circuit later. S this output goes to any analog signal on arduino. The code uses an external interrupt on the arduino s digital pin 2.

Uploading the flow meter code to the arduino and measuring water flow rate. For this purpose using interrupts is a best choice. In this tutorial we will be hooking up a flow sensor to an arduino uno to measure liquid flow. There is a small calculation in the code which i will explain in the further sections.

Note that the water flow sensor is not a power hungry type. This project is very basic.
