YF-S201 Hall Effect Water Flow Meter / Sensor
VAT inclusive; Computed calculations added locally.
Overview
Monitor water usage and flow in real time with the YF-S201 Hall Effect Water Flow Sensor. This practical sensor combines a mechanical rotor with a Hall effect sensing mechanism to produce electrical pulses as water passes through the flow channel.
By counting the output pulses, a microcontroller can determine the approximate water flow rate and total volume of water passing through the system. This makes the YF-S201 useful for automatic water dispensers, irrigation systems, smart water monitoring, liquid-flow projects, DIY automation, and IoT applications.
The sensor is easy to integrate with popular development platforms such as Arduino and ESP32, making it a convenient choice for electronics enthusiasts and engineers developing water-management and monitoring systems.

Product Technical Information
Technical Details
The YF-S201 Hall Effect Water Flow Meter / Sensor is designed to detect and measure the flow of water through a pipe. Inside the sensor is a small rotor that rotates as water passes through the flow channel. A Hall effect sensor detects the rotor's movement and generates a pulse signal corresponding to the flow.
A compatible microcontroller can count these pulses to estimate the flow rate and calculate the total amount of water that has passed through the sensor. The exact relationship between pulse frequency and flow rate should be calibrated for the specific installation and operating conditions.
The YF-S201 is particularly useful in projects where water consumption or flow needs to be monitored electronically. It can be integrated into Arduino and ESP32-based systems, as well as various automated water-control and IoT applications.
