Durante la escasez mundial de chips, tap\u00f3 un agujero bastante grande con forma de Raspberry Pi en el <u>Inventario de frambuesa Pi<\/u> y proporcion\u00f3 a los fabricantes una plataforma IoT (Internet de las cosas) de bajo costo y f\u00e1cil de usar.  Seguro que no es el primer microcontrolador conectado a Internet (podemos hablar de ese honor en los comentarios), pero para muchos <u>Frambuesa Pi<\/u> fans, fue su primer paso en el maravilloso mundo de los microcontroladores. <\/p>\n<p>Mientras que Raspberry Pi ejecuta un sistema operativo Linux completo, Raspberry Pi Pico W depende del firmware para proporcionar una capa en la que podemos escribir nuestro c\u00f3digo.  MicroPython es uno de los lenguajes oficialmente admitidos y ha experimentado muchas mejoras para adaptarse a Raspberry Pi Pico.  Una mejora fue la inclusi\u00f3n de urequests (microsolicitudes) que permiten a nuestro Pico W enviar y recibir solicitudes HTTP.<\/p>\n<aside class=\"hawk-nest\" data-render-type=\"fte\" data-skip=\"dealsy\" data-widget-type=\"seasonal\"\/>\n<p>En este procedimiento, usaremos urequests junto con <u>ntfy.sh<\/u>, un servicio y una aplicaci\u00f3n gratuitos para dispositivos Android y Apple que pueden interceptar mensajes de dispositivos IoT y mostrarlos en su dispositivo.  Lo vamos a utilizar para enviar alertas a nuestro m\u00f3vil Android, alertas que se activan mediante un sensor PIR (Infrarrojos Pasivo) que detecta movimiento en una habitaci\u00f3n. <\/p>\n<p>Ntfy.sh es un servicio notablemente eficaz y sencillo.  En lugar de instalar un m\u00f3dulo Python\/MicroPython espec\u00edfico, funciona con solicitudes para enviar mensajes desde la Raspberry Pi Pico W usando un tema espec\u00edfico (muy similar a c\u00f3mo funciona MQTT).  Nuestro dispositivo Android\/iOS est\u00e1 suscrito a este tema y recibe las notificaciones del Pico W.<\/p>\n<p>Estamos limitados a enviar texto en Raspberry Pi Pico W, pero este proyecto tambi\u00e9n se puede usar con Raspberry Pi SBC y la c\u00e1mara oficial Raspberry Pi para <u>enviar imagenes<\/u> (o cualquier otra forma de apego) cuando ocurre un evento.  Indique si un p\u00e1jaro se est\u00e1 alimentando de su comedero para p\u00e1jaros o si hay alguien en su jard\u00edn trasero.  Para ver un ejemplo sobre c\u00f3mo usar im\u00e1genes con ntfy.sh, echa un vistazo a nuestro <u>c\u00f3mo usar diccionarios<\/u> tutorial.<\/p>\n<h2 id=\"building-the-circuit\">Construyendo el circuito<\/h2>\n<figure class=\"van-image-figure  inline-layout\" data-bordeaux-image-check=\"\">\n<div class=\"image-full-width-wrapper\">\n<div class=\"image-widthsetter\" style=\"max-width:984px;\">\n<p class=\"vanilla-image-block\" style=\"padding-top:110.98%;\"><picture><source type=\"image\/webp\" alt=\"Send Alerts From Raspberry Pi Pico W\" class=\"expandable lazy-image-van\" onerror=\"if(this.src &amp;&amp; this.src.indexOf('missing-image.svg') !== -1)return true;;this.parentNode.replaceChild(window.missingImage(),this)\" data-normal=\"https:\/\/vanilla.futurecdn.net\/tomshardware\/media\/img\/missing-image.svg\" data-srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/jAHVkQWj5C3Am8n7Xp3ZKh-320-80.png.webp 320w, https:\/\/cdn.mos.cms.futurecdn.net\/jAHVkQWj5C3Am8n7Xp3ZKh-480-80.png.webp 480w, https:\/\/cdn.mos.cms.futurecdn.net\/jAHVkQWj5C3Am8n7Xp3ZKh-650-80.png.webp 650w, https:\/\/cdn.mos.cms.futurecdn.net\/jAHVkQWj5C3Am8n7Xp3ZKh-970-80.png.webp 970w, https:\/\/cdn.mos.cms.futurecdn.net\/jAHVkQWj5C3Am8n7Xp3ZKh-1024-80.png.webp 1024w, https:\/\/cdn.mos.cms.futurecdn.net\/jAHVkQWj5C3Am8n7Xp3ZKh-1200-80.png.webp 1200w\" data-sizes=\"(min-width: 1000px) 970px, calc(100vw - 40px)\" data-original-mos=\"https:\/\/cdn.mos.cms.futurecdn.net\/jAHVkQWj5C3Am8n7Xp3ZKh.png\" data-pin-media=\"https:\/\/cdn.mos.cms.futurecdn.net\/jAHVkQWj5C3Am8n7Xp3ZKh.png\"\/><source type=\"image\/png\" alt=\"Send Alerts From Raspberry Pi Pico W\" class=\"expandable lazy-image-van\" onerror=\"if(this.src &amp;&amp; this.src.indexOf('missing-image.svg') !== -1)return true;;this.parentNode.replaceChild(window.missingImage(),this)\" data-normal=\"https:\/\/vanilla.futurecdn.net\/tomshardware\/media\/img\/missing-image.svg\" data-srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/jAHVkQWj5C3Am8n7Xp3ZKh-320-80.png 320w, https:\/\/cdn.mos.cms.futurecdn.net\/jAHVkQWj5C3Am8n7Xp3ZKh-480-80.png 480w, https:\/\/cdn.mos.cms.futurecdn.net\/jAHVkQWj5C3Am8n7Xp3ZKh-650-80.png 650w, https:\/\/cdn.mos.cms.futurecdn.net\/jAHVkQWj5C3Am8n7Xp3ZKh-970-80.png 970w, https:\/\/cdn.mos.cms.futurecdn.net\/jAHVkQWj5C3Am8n7Xp3ZKh-1024-80.png 1024w, https:\/\/cdn.mos.cms.futurecdn.net\/jAHVkQWj5C3Am8n7Xp3ZKh-1200-80.png 1200w\" data-sizes=\"(min-width: 1000px) 970px, calc(100vw - 40px)\" data-original-mos=\"https:\/\/cdn.mos.cms.futurecdn.net\/jAHVkQWj5C3Am8n7Xp3ZKh.png\" data-pin-media=\"https:\/\/cdn.mos.cms.futurecdn.net\/jAHVkQWj5C3Am8n7Xp3ZKh.png\"\/><\/picture><\/p>\n<\/div>\n<\/div><figcaption itemprop=\"caption description\" class=\" inline-layout\"><span class=\"credit\" itemprop=\"copyrightHolder\">(Cr\u00e9dito de la imagen: Tom&#8217;s Hardware)<\/span><\/figcaption><\/figure>\n<p>El circuito de este proyecto es incre\u00edblemente simple y est\u00e1 dise\u00f1ado espec\u00edficamente.
