Hall Effect Sensor Module – RPM & Speed Sensor

The Hall Effect Sensor Module – RPM & Speed Sensor is a precise, non-contact magnetic field detection device designed for use with Arduino, Raspberry Pi, and microcontroller projects. It converts magnetic field variations into digital pulses, allowing you to measure rotational speed, shaft position, or motor RPM efficiently.

This sensor operates using the Hall Effect principle, where a voltage difference is produced across a conductor in response to a magnetic field. It’s a robust, durable, and reliable component for robotics, motion detection, and industrial automation systems.

Whether you’re creating a motor control system, tachometer, or wheel encoder, this sensor module delivers accurate, real-time speed readings.
