O geofone \u00e9 um instrumento de medi\u00e7\u00e3o que servem para escutar vibra\u00e7\u00f5es da terra. No nosso caso \u00a0ele\u00a0serve para registrar ondas s\u00edsmicas e tremores, \u00a0mas existem o geofone que tem a fun\u00e7\u00e3o de\u00a0localizar vazamentos subterr\u00e2neos.<\/p>\n
Apesar do t\u00edtulo dizer “Geofone”, este circuito n\u00e3o se trata verdadeiramente de um geofone e sim de um detector de vibra\u00e7\u00f5es<\/strong>.<\/p>\n
Detector de Terremoto (\u00a0Geofone )<\/h2>\n
Existem in\u00fameros tipos de geofones, cada um com capacidade, tecnologia\u00a0e usos diferente. Por curiosidade se este detector tiver uma\u00a0frequ\u00eancia de trabalho de 14 Hz, ele ir\u00e1 reconhecer com precis\u00e3o apenas frequ\u00eancias de ondas de tremores a partir deste valor.<\/p>\n
Outra caracter\u00edstica \u00a0consiste na sua capacidade de registrar ondas s\u00edsmicas P ou S, ou ainda os dois tipos de ondas.<\/p>\n
<\/p>\n
O\u00a0circuito eletr\u00f4nico acima \u00e9 de um geofone caseiro, uma especie de detector de vibra\u00e7\u00f5es, ele \u00e9 feito a partir de um im\u00e3 bem forte, uma bobina de fio e um el\u00e1stico.<\/p>\n
O circuito \u00e9 sens\u00edvel o suficiente para detectar as vibra\u00e7\u00f5es de um pessoa caminhando nas proximidades. Ele pode ser usado como um detector de vibra\u00e7\u00f5es, sismo e tremor.<\/p>\n
