1 –  Introducci\u00f3n.<\/b><\/span>
\n
<\/b><\/span>
\n<\/p>\n

\n<\/div>\n
\nNuestra pr\u00e1ctica consiste en un dispositivo que medir\u00e1 la temperatura y  humedad y las notificar\u00e1 mediante una pantalla LCD.<\/span><\/div>\n
\nCon el fin de llevar a cabo un recopilatorio con los diferentes pares temperatura-humedad los guardaremos en una especie de ‘base de datos online’. Posteriormente este recopilatorio nos servir\u00e1 para realizar una comparativa entre los diferentes valores a lo largo del a\u00f1o.<\/span><\/div>\n
\n<\/div>\n
\n<\/div>\n
\n<\/div>\n
\n2 –  Materiales usados.<\/span> <\/b><\/div>\n
\n<\/div>\n
\n<\/div>\n
\n<\/div>\n
\n– Placa Arduino Uno (proporcionado por el profesor).<\/span><\/div>\n
\n– Modulo pantalla LCD 16×2 + interfaz I2C = 7,19 \u20ac<\/span><\/div>\n
\n– Soldadura pantalla LCD = 5 <\/span>\u20ac<\/span><\/div>\n
\n– Ethernet Shield w5100 = 12,09 <\/span>\u20ac<\/span><\/div>\n
\n– Placa board ZY = 6,85 <\/span>\u20ac<\/span><\/div>\n
\n– DHT22 sensor = 7,44 <\/span>\u20ac<\/span><\/div>\n
\n– Cable 10 metros = 2,5 <\/span>\u20ac<\/span><\/div>\n
\n– Cables hembra = 1 <\/span>\u20ac<\/span><\/div>\n
\n
<\/b><\/span><\/div>\n
\nPresupuesto total : 42,07 <\/u><\/b><\/span>\u20ac<\/b> <\/u><\/b><\/div>\n
\n
<\/b><\/div>\n
\n<\/div>\n
\n3 –  Funcionamiento.<\/b><\/span><\/div>\n
\n
<\/span><\/b><\/div>\n
\nAl comenzar el programa el sensor de temperatura y humedad DHT22 env\u00eda la temperatura y humedad que detecta en el ambiente  y la guarda en las variables ‘temp<\/b>‘ y ‘hum<\/b>‘ respectivamente.<\/span><\/div>\n
\nEstos valores ser\u00e1n ense\u00f1ados por pantalla y se actualizar\u00e1n cada cierto tiempo (dado por la instrucci\u00f3n ‘delay<\/b>‘).<\/span><\/div>\n
\n<\/div>\n
\n<\/div>\n
\n<\/div>\n
\n                             <\/a><\/div>\n
\n<\/div>\n
\n<\/div>\n
\n<\/div>\n
\n
<\/span><\/div>\n
\nPor otro lado, hemos querido a\u00f1adir a nuestro proyecto la funcionalidad de poder visualizar la temperatura y humedad con independencia de la pantalla LCD. Para ello hemos usado el ethernet shield w5100 para poder conectarnos a Internet y conectarnos a una API donde recopilar nuestros datos: la API de ThingSpeak.<\/span><\/div>\n
\n<\/div>\n
\n<\/div>\n
\nAPI de ThingSpeak:<\/b><\/span><\/u><\/div>\n
\n
<\/span><\/div>\n
\nSu especialidad es trabajar con datos. Es una API abierta para el Internet de las Cosas que permite recopilar, almacenar, analizar, visualizar y actuar sobre la informaci\u00f3n recogida en sensores (en nuestro caso DHT22) y dispositivos como aplicaciones web y m\u00f3viles, redes sociales como Twitter… etc.<\/span><\/div>\n
\n
<\/span><\/div>\n
\nFunciona con canales por lo que hemos creado un canal en el cual iremos recopilando la informaci\u00f3n de nuestro sensor a partir de la cual visualizaremos gr\u00e1ficos.<\/span><\/div>\n

\n6 – <\/span>Problemas e inconvenientes que hemos tenido.<\/span><\/b><\/div>\n
\n
<\/b><\/span><\/div>\n
\nDurante el montaje del proyecto nos encontramos con algunos problemas. <\/span><\/div>\n
\n
<\/span><\/div>\n
\nUno de ellos lo tuvimos con la pantalla LCD que ven\u00eda con un m\u00f3dulo de interfaz I2C que, en principio, ayuda a regular la potencia de la pantalla y facilita el montaje. Nuestro error fue no darnos cuenta de que ten\u00edamos que ajustar el potenci\u00f3metro ajustando as\u00ed el contraste de la LCD y poder ver lo que se imprim\u00eda.<\/span><\/div>\n
\n
<\/span><\/div>\n
\nPor otro lado, tuvimos la idea de reproducir la salida del DHT22 mediante un altavoz. Para ello compramos un m\u00f3dulo MP3 llamado DF Player Mini Mp3. En principio todo iba bien pero tuvimos problemas con la corriente y se nos fundi\u00f3. Al haberse dado este problema cerca de la presentaci\u00f3n de nuestro proyecto fue imposible conseguir otro m\u00f3dulo por lo que descartamos la idea para este presente proyecto. No descartamos la idea de implementarlo en un futuro.<\/span>
\n
<\/span>
\nA\u00f1adir tambi\u00e9n que nos encontramos con ligeros errores a la hora de conectarnos con la base de ThingSpeak, aunque no fueron dif\u00edciles de resolver.<\/span><\/div>\n
\n
<\/span><\/div>\n
\nY por \u00faltimo, y no por ello menos importante, tenemos presente el problema de la portabilidad de nuestro proyecto pues somos conscientes de que un dispositivo que mide la temperatura y humedad debe ser m\u00e1s peque\u00f1o. <\/span><\/div>\n
\n
<\/b><\/span><\/div>\n
\n7 – <\/span>Mejoras y complementos futuros del proyecto.<\/span><\/b><\/div>\n
\n<\/div>\n
\nLas mejoras que proponemos son las siguientes:<\/span><\/div>\n
\n
<\/span><\/div>\n
\n– Reducir el tama\u00f1o del cableado y de la placa base con el fin de conseguir que el dispositivo sea portable.<\/span><\/div>\n
\n– Sustituir la ethernet shield por una WiFi, pues es m\u00e1s incomodo encontrar un puerto Ethernet al que enchufarlo que conectarlo a una red inal\u00e1mbrica.<\/span><\/div>\n
\n– Encontrar un dise\u00f1o visual atractivo y eficiente.<\/span><\/div>\n
\n– Implementar una voz que lea la temperatura y humedad (similar a SparkFun VoiceBox SHield).<\/span><\/div>\n
