The water flow sensor consists of a plastic valve body a water rotor and a hall effect sensor.
Water flow sensor switch arduino.
When the water flows through the rotor rotor rolls and the speed of it changes with a different rate of flow.
In this project i will talk a little bit water flow sensors how a water flow sensor works and how to interface a simple water flow sensor with arduino.
Digiten g1 2 water flow hall sensor switch flow meter flowmeter counter 1 30l min.
Water flow sensors are simple devices which can aid us in measuring the flow of a liquid.
In this tutorial you will learn how to use one water flow sensor with an arduino board.
For this particular project we are going to use the yf s201 water flow sensor which uses a hall effect to sense the flow rate of the liquid.
We will interface the water flow sensor with arduino and lcd and program it to display the volume of water which has passed through the valve.
