Water Flow Sensor Arduino

Have fun with your new arduino flow rate sensor.

Water flow sensor arduino.

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. How to use water flow sensor arduino tutorial. It requires only 5v vcc and gives pulse output the sensor needs to be tightly fitted between water pipeline. 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.

It draws a maximum. You can use it in your gardening system or interface it with an lcd display for other applications that require you to measure water flow rate and quantity. The complete water flow sensor arduino code is given at the bottom of the page. When the water flows through the rotor rotor rolls and the speed.

The code for the arduino water flow sensor interface is given below. The sensor s output pin is connected to pin 2 of. The water flow sensor for flow rate volume measurement using arduino works on the principle of the hall effect. In order to obtain this there is a small calculation.

Yf s201 water flow sensor. According to the hall effect a voltage difference is induced in a conductor transverse to the electric current and the magnetic field perpendicular to it. 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. The explanation of the code is as follows.

There is a small calculation in the code which i will explain in the further sections. 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 output of the project is to display the quantity of water flowing through the sensor in litres per hour as shown below. Note that the water flow sensor is not a power hungry type.

Connecting the water flow sensor to arduino requires minimal interconnection. 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.
