Keyes Hall Water Flow Sensor

The Keyes Hall Water Flow Sensor is an accessible fluid-measurement module designed for students, educators, and makers. It is ideal for anyone looking to add real-time liquid tracking to their coding and robotics projects.

Precise fluid measurement

This module utilises an internal magnetic rotor and a Hall-effect sensor to detect liquid movement. As water flows through, the rotor spins, generating pulses that correspond to the flow rate.

Versatile project integration

The sensor is highly compatible with popular microcontrollers, making it a great addition to DIY automation setups. It is ideal for building smart gardens, automatic pet feeders, or custom water-dispensing rigs.

Robust inline construction

Designed for simple installation, the sensor fits directly into your plumbing line. The secure casing ensures a tight seal to prevent leaks during operation.

Educational applications

An excellent resource for South African classrooms and coding clubs, this sensor helps students explore real-world physics and electronics. It provides a practical way to teach calibration, pulse counting, and data logging.
