- 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
- Proximity Sensing
- Valve Positioning
- Pulse Counting

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
- Other DIY Projects
