<\/iframe><\/p>\n<p>En este tutorial veremos como hacer un alcohol\u00edmetro, simple econ\u00f3mico y f\u00e1cil de hacer. Veremos el c\u00f3digo fuente, el armado del circuito todo paso a paso. El circuito impreso estar\u00e1 disponible totalmente gratis.<\/p>\n<p><strong>\u00bfQue es un alcohol\u00edmetro?<\/strong><\/p>\n<p>Es un dispositivo para medir la cantidad de alcohol presente en el aire espirado por una persona, \u00a0tambi\u00e9n puede\u00a0medir la cantidad de alcohol contenido en un l\u00edquido o gas.<\/p>\n<p><strong>M\u00f3dulo MQ3<\/strong><\/p>\n<p>Este sensor de alcohol es adecuado para detectar la concentraci\u00f3n de alcohol en su aliento, al igual que un alcohol\u00edmetro comercial. Tiene una alta sensibilidad y tiempo de respuesta r\u00e1pido. El sensor presenta una salida anal\u00f3gica resistiva basado en la concentraci\u00f3n de alcohol.<\/p>\n<p><strong>Algunos comentarios del sensor MQ3<\/strong><\/p>\n<p>Este sensor posee 4 pines dos de los cuales son de alimentaci\u00f3n, uno es una salida anal\u00f3gica (pin AD) y la otra una salida digital (pin DO), est\u00e1 ultima se puede regular su sensibilidad, por medio de un potenci\u00f3metro que posee la placa, notaran que al encender este m\u00f3dulo y conectarle un led este se enciende, ya que esta salida es invertida o negada (NOT). Este quiere decir que al no haber presencia de alcohol en el sensor el led estar\u00e1 encendido y si supera el umbral de seteado con el potenciometro este se apagar\u00e1. Este es muy \u00fatil si no queremos utilizar ning\u00fan microcontrolador, ni arduino, con este m\u00f3dulo solamente podemos tener un alcohol\u00edmetro muy simple s\u00f3lo alimentando al m\u00f3dulo y nada m\u00e1s.<\/p>\n<p>En cuanto encendamos este m\u00f3dulo, comenzar\u00e1 a calentarse, tenemos que esperar unos minutos(alrededor de 5) \u00a0para que el modulo se caliente y tengamos un censado correcto.<\/p>\n<hr \/>\n<p style=\"text-align: left;\">Tal vez pueda interesarte proyectos en arduino, pic, rob\u00f3tica, telecomunicaciones, suscribete en\u00a0<a

MQ3<\/p>\n<p>Descripci\u00f3n General<br \/>\nEste sensor detecta la concentraci\u00f3n de alcohol en aire. Simplemente se conecta a una entrada anal\u00f3gica de un microcontrolador como Arduino y podremos medir la concentraci\u00f3n de alcohol.<br \/>\nPosee una salida anal\u00f3gica que indica la concentraci\u00f3n de alcohol en el ambiente (Cuanto mas alto el nivel de salida, mayor la concentraci\u00f3n de gas)<br \/>\nY tambi\u00e9n posee una salida digital que baja a 0 cuando la concentraci\u00f3n de alcohol supera el nivel prefijado con el preset.<br \/>\nArticulo ideal para usar con placas Arduino o cualquier microcontrolador (PIC, AVR, FREESCALE, etc)<\/p>\n<p>Especificaciones<br \/>\nVoltaje de Operaci\u00f3n: 5Vdc<br \/>\nIntegrado amplificador LM393 con ganancia variable mediante potenci\u00f3metro.<br \/>\n2 pines de salida (salida anal\u00f3gica y salida de nivel TTL).<br \/>\nSalida de nivel TTL v\u00e1lida de bajo nivel, se puede conectar directamente al microcontrolador.<br \/>\nSalida anal\u00f3gica de 0 ~ 5 V , el voltaje m\u00e1s alto equivale a una concentraci\u00f3n m\u00e1s alta.<br \/>\nCondiciones de trabajo: Temperatura ambiente:-10\u00b0C a 65\u00b0C, Humedad:=95% RH<\/p>\n<p>PCB<\/p>\n<p><a
