Description

The HS-S40P module integrates a Hall-effect sensor IC that responds to magnetic fields from either polarity, simplifying installation as orientation is not critical. It outputs a clean digital logic signal, transitioning high or low when a magnetic field of sufficient strength is detected, which is conditioned by an onboard comparator.

Designed for embedded electronics and DIY projects, the module’s compact footprint and standard mounting holes facilitate integration into enclosures and mechanical assemblies. Its wide voltage compatibility ensures seamless operation with common 3.3V and 5V microcontroller platforms, providing a reliable solution for non-contact switching, security systems, and rotational speed measurement.

Key Features

  • Omnipolar Magnetic Detection: Sensitive to both north and south magnetic poles, eliminating polarity alignment concerns during installation.
  • Digital Output Interface: Provides a clean, Schmitt-triggered digital signal for direct reading by microcontrollers.
  • Broad Voltage Compatibility: Operates from 3.3V to 5.5V DC, compatible with Arduino, ESP32, Raspberry Pi, and other common logic families.
  • Robust Connector: Utilizes a PH2.0 4-pin terminal for a secure and vibration-resistant electrical connection.
  • Engineered for Integration: Compact PCB layout with clearly labeled GND (G), VCC (V), and Signal (S) pins alongside pre-drilled mounting holes.
  • Stable Performance: Onboard circuitry ensures stable operation across its specified voltage and temperature range.

Applications

  • Door/Window Security Sensors: Detect open/close status in alarm systems using a mounted magnet.
  • Rotational Speed Sensing: Measure RPM in motors or fans by detecting passing magnets on a rotor.
  • Non-contact Position Detection: Determine the presence or position of a magnetic object in automated machinery.
  • DIY Electronics Projects: Integrate into Arduino or Raspberry Pi projects for magnetic trigger events.

Frequently Asked Questions

What is the operating voltage range for the HS-S40P module?

The HS-S40P module is designed to operate from 3.3V to 5.5V DC. This wide range makes it directly compatible with most 3.3V logic microcontrollers (like ESP32) and 5V systems (like standard Arduino boards) without requiring a level shifter.

How do I connect and interface the HS-S40P with an Arduino?

Connect the module's VCC pin to Arduino's 5V (or 3.3V), GND to GND, and the digital signal (S) pin to any digital input pin on the Arduino. The output will be a logic HIGH or LOW depending on the presence of a magnetic field. No special libraries are required; use digitalRead() to monitor the pin state.

What does 'omnipolar' mean for this Hall sensor?

Omnipolar means the sensor reacts to both the north and south poles of a magnet. Unlike unipolar sensors that only respond to one polarity, the HS-S40P will trigger its digital output when either pole is brought within its detection range, simplifying installation as magnet orientation is not critical.

What is the function of the PH2.0 connector on this module?

The PH2.0 4-pin connector provides a secure, locking connection for power (VCC), ground (GND), and the digital output signal (S). This interface is more reliable than plain header pins for applications subject to vibration or movement, ensuring stable electrical contacts.
