Arduino Water Flow Sensor Code

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.

There is a small calculation in the code which i will explain in the further sections. Water flow sensor for flow rate volume measurement using arduino code along with. The output of the project is to display the quantity of water flowing through the sensor in litres per hour as shown below. Communication started with 9600 baud void loop int sensor analogread a1.

Upload the flow meter code to your arduino. This project is very basic. The explanation of the code is as follows. When the water flows through the rotor rotor rolls and the speed.

Wrote serial port let s prepare the circuit. 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. Uploading the flow meter code to the arduino and measuring water flow rate. Anyone can do it.

The water sensor has 3 output pins. This is used to read the pulses coming from the flow meter. 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 tutorial we will be hooking up a flow sensor to an arduino uno to measure liquid flow.

The sensor s output pin is connected to pin 2 of. The complete water flow sensor arduino code is given at the bottom of the page. The code uses an external interrupt on the arduino s digital pin 2. Incoming analog signal read and appointed sensor serial println sensor.

When the arduino detects the pulse it immediately triggers the pulsecounter function. Note that the water flow sensor is not a power hungry type. 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.

Arduino have to count the number of pulses outputted by the water flow sensor. Lets begin and make circuit i will explain the code and circuit later. How to use water flow sensor arduino tutorial. For this purpose using interrupts is a best choice.

In order to obtain this there is a small calculation. It draws a maximum of 15 20ma at 5v dc input.
