Descripción
Instrumento de ruido básico que mide el nivel de sonido del ambiente circundante
Conversión simple: salida analógica lineal
Correspondencia lineal: 30~130 dBA, no se requiere algoritmo complejo
Admite un voltaje de entrada amplio de 3.3~5,0 V y una salida de voltaje de 0,6~2,6 V
Se puede aplicar a pruebas de ruido ambiental, como estaciones de monitoreo de ruido en autopistas, etc.
El Medidor de Nivel de Sonido Analógico Gravity (también conocido como medidor de decibelios, medidor de ruido) es un instrumento de medición de ruido básico. Este medidor de nivel de sonido es compatible con Arduino. Puede medir con precisión el nivel de sonido del entorno circundante. Este producto usa un circuito de instrumento y un micrófono de bajo ruido. Es compatible con un amplio voltaje de entrada de 3,3~5,0 V y una salida de voltaje de 0,6~2,6 V.
El valor de decibelios es lineal con el voltaje de salida, lo que conduce a una conversión simple, sin algoritmos complejos. El medidor de nivel de sonido se usa ampliamente en la detección de ruido ambiental, como la estación de monitoreo de ruido de la carretera, la supervisión del ruido de la sala, etc.
The widely available much simpler boards containing just the small electret mics used in this device, with an amplifier, are good for little more than listening for a loud noise against a quieter background. This device gives a reasonable approximation to sound measured in decibels and it's trivially easy to use because of its analog voltage output that's linearly related to sound in units of dBA. If you really want to monitor sound levels with Arduinos, this is the way to do it.
