Necesito un modulo de microfono similar al hw-484, que opciones hay??

flux

Un módulo similar al HW-484 suele referirse a un módulo de micrófono electret con amplificador/comparador, usado para detección de sonido con Arduino. Opciones comunes:
  • KY-038 / KY-037: electret + LM393, salida analógica y digital ajustable con potenciómetro. Muy parecido al HW-484.
  • MAX4466 electret amplifier: salida analógica amplificada, mejor calidad para medir nivel de audio; no trae salida digital.
  • MAX9814 electret AGC: amplificador con control automático de ganancia; útil si el volumen cambia mucho.
  • INMP441 / ICS-43434: micrófono MEMS digital I2S; mejor calidad, pero requiere microcontrolador con I2S.
  • SPH0645LM4H: MEMS I2S, compacto y común en proyectos con ESP32.
  • Adafruit / SparkFun Sound Detector: módulos más confiables, algunos incluyen salida “envelope” para nivel de sonido.
Para tu proyecto con Arduino UNO R3, la opción más directa sería KY-038/KY-037 si quieres algo equivalente al HW-484, o MAX4466/MAX9814 si necesitas una señal analógica más limpia para medir intensidad de sonido.
No pude modificar el proyecto ni buscar componentes en la librería porque ahora mismo no hay ACUs disponibles para usar funciones AI.
