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
