  • The module has no trigger and outputs low level; the module has trigger and outputs high level.
  • The sensitivity is adjustable (fine adjustment).
  • There is signal output when there is magnetic field cutting.
  • The circuit board output switch, you can directly connect to the microcontroller or our relay module, buzzer module.
  • Can be used for motor speed / position detection and other occasions.

Hall Effect Sensor Module

Hall Effect Sensor Module is used to detect the proximity of a magnet. It is very much smaller in size. When the magnetic field rises above a threshold level, the open-collector output transistor switches on, which pulls the logic-compatible output low and illuminates the onboard LED indicator.

It's fast (The turn-on threshold is 35-450 Gauss, the minimum hysteresis is 20 Gauss, and the operating voltage range is 4.5 - 24 volts. This module uses the Allegro MicroSystems A3144EUA sensor. It has a 3-pin interface, signal, V+, and GND.

To use this sensor/switch, place a 10K pull-up resistor between the "S" pin and the middle pin (+), and connect the "-" pin to the ground. Supply voltage to the middle pin. The "S" pin will go low (gets pulled to the ground) and the onboard LED indicator will turn on when a magnet is brought near.

Pin Description:

  • VCC : 2.3 volts to 5.3 Volts
  • GND : power supply ground
  • AOUT (analog sensor output) : Arduino/ MCU input
  • DOUT (digital sensor output) : Arduino/MCU input

Applications: 

  • Motor shaft speed measurement (shaft encoder)
  • Object position detection
  • Docking Detection
  • Door Open and Close Detection

1. What is Hall Effect sensor module?

  • The Hall Effect Sensor Module is used to detect the presence of a magnetic field. The output of the module goes high in the presence of a magnetic field and it becomes low in the absence of a magnetic field. 

2. Where do we use Hall Effect sensor module?

  • The Hall Effect sensor module is used for 
    • Motor shaft speed measurement (shaft encoder)
    • Object position detection, Docking Detection
    • Door Open and Close Detection
    • Proximity Sensing
    • Valve Positioning
    • Pulse Counting
