4. Working Principle
The Hall effect sensor module operates based on the Hall effect:
- Power Connection: The module connects to a power supply via GND and VCC ports, operating within 3.3V to 5V to ensure proper functionality.
- Signal Control: When a magnetic field is detected, the module outputs a high-level signal; it outputs a low-level signal in the absence of a magnetic field.
- Connection Configuration: The red anti-reverse connector and matching cable ensure safe and efficient connections, minimizing wiring errors.

5. Pin Description
| Pin Name | Description |
|----------|-----------------------------------------------------------------------------|
| VCC | Positive power supply (3.3V to 5V input) |
| GND | Negative power supply connection |
| S | Signal output pin; outputs high level when magnetic field is detected |

- VCC: Connects to the positive terminal of the power supply. Ensure the voltage remains within 3.3V–5V to prevent damage.
- GND: Connects to the negative terminal (ground) for stable operation.
- S (Signal Pin): Outputs a high-level signal when a magnetic field is detected, and a low-level signal in its absence.
