Sensitive Module with Digital Output for Door Detection, RPM Measurement and Positioning

The KY-003 Hall Effect sensor module is a magnetic switch that detects the presence of a magnetic field.

When no magnet is present, the output is HIGH, and when a magnet is detected, it switches to LOW, enabling easy digital detection.

It uses the A3144 Hall-effect sensor IC, known for stability and reliability in magnetic sensing applications.

The module provides a digital output, making it simple to interface with microcontrollers without analog processing.


 Key Features:

  • ✔️ Hall effect magnetic sensor
  • ✔️ Digital output (HIGH/LOW)
  • ✔️ Arduino / ESP32 / Raspberry Pi compatible
  • ✔️ Built-in LED indicator
  • ✔️ Compact size

 Technical Specifications:

  • Sensor chip: A3144
  • Voltage: 4.5V – 24V
  • Output: Digital
  • Current: ~3–8 mA
  • Temp range: -40°C to +85°C
