A simple analog Hall effect sensor module for detecting magnetic fields with Arduino. When a magnet is detected, the on-board LED turns on and the analog output changes proportionally to the field strength — making it easy to detect both the presence and relative proximity of a magnet.

Key Features

  • Analog Output – Proportional signal for magnetic field strength detection
  • On-Board LED – Visual indicator when a magnetic field is detected
  • 3-Pin Interface – Simple connection to any Arduino analog input
  • 3.3V / 5V Compatible – Works with both voltage levels

Specifications

  • Output – Analog
  • Supply Voltage – 3V to 5V
  • Dimensions – 20 × 11 × 12mm

Wiring

  • Y (S) – Analog input (e.g. Arduino A5)
  • G (-)GND
  • R (+) – Power (3V or 5V)

Ideal For

  • Magnetic field detection and proximity sensing
  • Door and window open/close detection
  • RPM and rotation sensing
  • Arduino beginner sensor projects

Package Contents

  • 1× Analog Hall Effect Sensor Module

Jargon buster

Plain-language definitions for the technical terms used above.

GND
GND is the ground or reference connection (0 V) for a circuit. When connecting two devices together, their grounds must be joined so both agree on what counts as a low or high signal.
LED
A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
