Water Flow Sensor Arduino

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.

Water flow sensor arduino.

Use this arduino flow rate sensor with a solenoid valve to monitor and control the water used. In this tutorial we will be hooking up a flow sensor to an arduino uno to measure liquid flow. The water flow sensor for flow rate volume measurement using arduino works on the principle of the hall effect. The explanation of the code is as follows.

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 requires only 5v vcc and gives pulse output the sensor needs to be tightly fitted between water pipeline. 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. 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.

Note that the water flow sensor is not a power hungry type. Have fun with your new arduino flow rate sensor. This water flow sensor has only three wires and it can be easily interfaced between any microcontroller and arduino board. 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. Connecting the water flow sensor to arduino requires minimal interconnection. 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.

There is a small calculation in the code which i will explain in the further sections. 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. 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. When the water flows through the rotor rotor rolls and the speed.
