Hall Effect Sensor Module is used to Detect the proximity of a magnetic field if it present or absent nearby.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 on board LED indicator.

This compact sensor detects magnetic fields with precision, using the A3144EUA sensor. Ideal for motion sensing, proximity detection, and motor speed monitoring. Easy to integrate with microcontrollers via a simple 3-pin interface and onboard LED indicator. Operates on 2.3V to 5.3V
Unlock magnetic detection in your electronics projects with this compact and reliable Hall Effect Sensor Module. Designed for precision and ease of use, this module responds when a magnetic field crosses a certain threshold—perfect for detecting motion, rotation, or object presence without physical contact. With onboard LED indication and a clean digital output, it’s beginner-friendly yet accurate enough for advanced applications. A simple 3-pin interface—Signal (S), VCC, and GND—makes it easy to hook up with Arduino, Raspberry Pi, or any microcontroller.
This module is based on the A3144E Hall switch sensor and it is designed to be used in applications requiring magnetic field sensing. This module used to detect the presence of magnetic field. Whenever a magnetic field come near to sensor within its detection distance, it will output a signal on the output pin.
This module can be used in many projects like making a contactless switch for door alarm. It can also be used in making speedometer for car or a bike. If a magnet is attached to the wheel and this module in the stationary body, we can know the time taken to complete a cycle and by doing further calculation, we can calculate the speed. It can be used for sensing motor speed, position and more.
It features two outputs: AO, the analog signal output and DO, the digital output, after being passed through a voltage comparator. The Hall sensor outputs a low level voltage when magnetic field is detected.
