5. Instruções de operação
The KY-003 module operates by detecting changes in a magnetic field. When a magnetic field of sufficient strength and appropriate polarity is brought near the sensor, its digital output pin will change state.
Operação básica:
- Ligar: Ensure the module is correctly wired and powered with 5V DC.
- Detecção de Campo Magnético: Bring a magnet close to the Hall effect sensor component on the module.
- Sinal de saída: The digital output pin will typically be HIGH (5V) when no magnetic field is detected, and switch to LOW (0V) when a magnetic field is present, or vice-versa, depending on the specific Hall sensor IC and its configuration. Refer to the datasheet of the specific Hall sensor IC (e.g., 44E, A3144) for exact behavior.
- Microcontroller Reading: Your microcontroller can read the state of the digital output pin to determine if a magnetic field is detected.
Por exemploample, in an Arduino sketch, you would use `digitalRead()` on the connected pin to get the sensor's state.
