Arduino Water Flow Sensor Code

The output of the project is to display the quantity of water flowing through the sensor in litres per hour as shown below.

Arduino water flow sensor code.

When the water flows through the rotor rotor rolls and the speed. Arduino have to count the number of pulses outputted by the water flow sensor. Uploading the flow meter code to the arduino and measuring water flow rate. Incoming analog signal read and appointed sensor serial println sensor.

Upload the flow meter code to your arduino. Water flow sensor for flow rate volume measurement using arduino code along with. 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.

There is a small calculation in the code which i will explain in the further sections. The sensor s output pin is connected to pin 2 of. Anyone can do it. The explanation of the code is as follows.

This project is very basic. How to use water flow sensor arduino tutorial. The code uses an external interrupt on the arduino s digital pin 2. 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.

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. Wrote serial port let s prepare the circuit. 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. The complete water flow sensor arduino code is given at the bottom of the page.

Communication started with 9600 baud void loop int sensor analogread a1. In order to obtain this there is a small calculation. For this purpose using interrupts is a best choice. When the arduino detects the pulse it immediately triggers the pulsecounter function.

Note that the water flow sensor is not a power hungry type. 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. In this tutorial we will be hooking up a flow sensor to an arduino uno to measure liquid flow. The water sensor has 3 output pins.

It draws a maximum of 15 20ma at 5v dc input. This is used to read the pulses coming from the flow meter.
