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. When the water flows through the rotor, rotor rolls and the speed of it changes with a different rate of flow.

Firstly, we will see an introduction of flow rate sensors that is why and where to use flow sensors. Secondly, we will discuss its pinout diagram and working. In the end, we will see how to interface the YF-S201 Water flow sensor with Arduino and its programming in Arduino IDE.

Jun 28, 2015 · In this tutorial we will be connecting a liquid flow sensor to an Arduino and writing code to measure the amount of liquid passing the sensor.

May 20, 2024 · In this Arduino project, we will learn what is a water flow sensor, how a water flow sensor works, and how to interface it with Arduino to measure the water flow rate and calculate the volume of the water passed through the sensor.

Feb 2, 2025 · 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.

Mar 17, 2022 · In this project, we are going to build a water flow sensor using Arduino. 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.

May 29, 2022 · This project is about measuring water flow rate with YF-S201 Sensor and Arduino.

Mar 26, 2024 · In this project, I will show you how to interface a Water Flow Sensor with Arduino. Using this Arduino Water Flow Sensor tutorial as a reference, you can implement a system which can measure the quantity of water (or any liquid) flowing through a pipe.

May 11, 2020 · We use a water flow sensor to measure the water flow rate. The water flow rate is the volume of fluid that passes per unit time. People often use water flow sensor for automatic water heater control, DIY coffee machines, water vending machines, etc.

Jun 28, 2023 · This Arduino code for the water flow sensor detects the water flow rate in liters per hour and shows the observed value on the Arduino IDE’s serial monitor. When water goes through the valve, it starts to rotate the rotor.
