Whadda Hall Magnetic Switch Module Pack of 2

The Whadda Hall Magnetic Switch Module Pack of 2 is a two-module, Arduino-compatible sensor pack with a digital output for detecting magnetic fields in electronic projects. Each module features an onboard Hall voltage generator designed to detect changes in magnetic fields with precision.

Overview

Each module includes an integrated amplifier that boosts the generated Hall voltage, along with a Schmitt trigger that provides switching hysteresis for noise rejection. This circuitry supports stable, glitch-free operation in electrically noisy environments. The module provides a clean digital output through an open-collector configuration, and an onboard LED clearly indicates activation status, offering immediate visual feedback.

Pins are clearly labelled for Ground (GND), Power (+), and Signal output (S). Connection is straightforward using the supplied 3-pin male header, which suits quick prototyping and installation.

Key Features

• Arduino compatible, designed for integration with popular Arduino development boards and other 5V microcontroller systems
• Integrated Hall effect sensor with on-chip Hall voltage generator
• Schmitt trigger output (active low) with built-in hysteresis to prevent signal bouncing
• Onboard LED indicator for easy status monitoring
• Activates at approximately 30 Gauss and deactivates at 10 Gauss
• Standard 3-pin male header (GND, +5V, Signal)
• Compact design with a small footprint for space-constrained applications
• Supplied as a pack of two modules

Summary

This two-module pack suits projects that require more than one magnetic sensing point, including multiple projects or differential sensing setups. Its defined switching points and digital output make it a practical choice for magnetic field detection in 5V electronic systems.
