Keyestudio Hall Effect Magnetic Induction Sensor Module

The Keyestudio Hall Effect Magnetic Induction Sensor Module is a digital proximity sensor designed to detect magnetic materials. It is an excellent choice for South African students, educators, and makers looking to learn about magnetic fields or build non-contact switching projects.

Proportional magnetic detection

This module detects magnetic materials within a range of up to 3cm. The detection range is directly proportional to the strength of the magnetic field being sensed.

SFE reed switch technology

The sensor utilises the SFE Reed Switch magnetic field sensor for reliable detection. This makes it highly suitable for simple proximity and presence-sensing applications.

Digital on and off output

The module provides a clean digital output that switches between on and off states. This makes it incredibly easy to interface with standard microcontroller input pins.

Accessible learning resources

A dedicated wiki page tutorial is available to help you get up and running quickly. It is ideal for classroom demonstrations and beginner robotics projects.

Compact proximity sensing

Its small footprint allows for easy integration into tight spaces. It is perfect for building custom limit switches, security alarms, or rotational counters.
