En este tutorial crearemos un web server para el control de cualquier dispositivo, que se maneje por infrarrojos, como televisores, equipos de audio, DVD etc. Para ello vamos a usar el esp32 con dos sensores infrarrojos uno receptor, para capturar los comandos de mandos infrarrojos, y otro sensor emisor, para enviar el código obtenido, y de esa forma controlar el dispositivo electrónico hogareño. Analizaremos el código fuente, creado para tal fin, también hablaremos como hacer la aplicación que va a interactuar con el web server interno del esp32, y finalmente haremos una prueba del funcionamiento de todo este sistema.

Un Esp32
Características del módulo ESP32-T
Conectividad
El módulo ESP32 dispone de todas las variantes del WiFi:
- 802.11 b/g/n/e/i/n
- Wi-Fi Direct (P2P), P2P Discovery, P2P Group Owner mode and P2P Power Management
Esta versión nueva incluye la conectividad mediante Bluethoot de bajo consumo
- Bluetooth v4.2 BR/EDR and BLE
- BLE Beacon
Además, puede comunicarse mediante los protocoles SPI, I2C, UART, MAC Ethernet, Host SD
Prestaciones del microcontrolador
La CPU está formado por un SoC modelo Tensilica LX6 con las siguientes características y memoria
- Doble núcleo de 32 bits con velocidad de 160MHz
- Memoria ROM de 448 kBytes
- Memoria SRAM de 520kBytes
Dispne de 48 Pines
- 18 ADC de 12 bits
- 2 DAC de 8 bits
- 10 pines sensores de contacto
- 16 PWM
- 20 Entradas/salidas digitales
Alimentación y modos de consumo
Para un correcto funcionamiento del ESP32 es necesario subministrar un voltaje de entre 2,8V y 3,6V. La energía que consume depende del modo de funcionamiento. Contiene un modo, el Ultra Low Power Solution (ULP), en que se continúan realizando tareas básicas (ADC, RTC…) en el modo Sleep.
