Indicador de polución acústica (CIR1228S)

Written by: Newton C. Braga
Category: Banco de circuitos

 

Este circuito fue indicado en e la revista americana Electronics Hobbyst del verano de 1974. La revista ya no existe, pero el proyecto puede ser montado con facilidad, pues los componentes son comunes, excepto algunos que pueden ser sustituidos por equivalentes modernos como el Q1 que Puede ser cambiado por BC548 y el Q2 por un BC558. El micrófono debe ser una cápsula piezoeléctrica de alta impedancia. El circuito detecta la contaminación acústica en tres bandas, accionando un LED si los niveles son superiores. Los niveles sonoros más comunes para el ambiente en un artículo disponible en este sitio. El LED puede ser de cualquier tipo.
