    1. Hall Effect Sensor (3144): The heart of the module is the Hall Effect sensor, specifically the 3144 model. The Hall Effect is a phenomenon in physics where a voltage is generated across an electrical conductor when a magnetic field is applied perpendicular to the current flow. In the context of this module, the Hall Effect sensor can detect the presence and strength of a magnetic field.
    2. Module Components:
      • LED Indicator: There is usually an onboard LED that lights up when the sensor detects a magnetic field, providing a visual indication.
      • Comparator Circuit: The module often includes a comparator circuit that processes the analog signal from the Hall Effect sensor and converts it into a digital signal that can be easily read by a microcontroller or other digital devices.
    3. Operating Principle:
      • When a magnetic field is present near the sensor, it influences the behavior of the Hall Effect sensor.
      • The sensor outputs a voltage proportional to the strength of the magnetic field.
      • The comparator circuit then converts this analog signal into a digital signal, and the LED may be activated to indicate the presence of a magnetic field.
    4. Applications:
      • The KY-003 Hall Magnetic Sensor Module is commonly used in projects where the detection of magnetic fields is essential.
      • It can be used in various applications, such as proximity sensing, door/window contact switches, speed detection in rotating objects, and more.
    5. Interfacing:
      • The module typically has three pins: VCC (power supply), GND (ground), and OUT (output). Connect these to the corresponding pins on your microcontroller or development board.
