Sonda para altas temperaturas.

Conexionado:

CFG BUTTON = GPIO 0 // D3 botón configuración
status_led = GPIO 2 // D4
max6675 DO = GPIO 14 // D5
max6675 CS = GPIO 12 // D6
max6675 CLK = GPIO 13 // D7

Para acceder al modo de configuración WiFi, mantenga presionado el botón durante al menos 10 segundos.
Cuando está en modo de configuración WiFi, el dispositivo entra en modo Punto de acceso WiFi y el LED de estado se enciende.

Para ingresar o cambiar la configuración:
- Inicie sesión en https://cloud.supla.org (el registro es gratuito) y Active el registro para nuevo dispositivo.
- Conéctese a la WiFi llamada "K_Probe" desde cualquier ordenador con una tarjeta de red inalámbrica y un navegador de Internet.
- Abra la Página: http://192.168.4.1
- Pulse en configure WiFi.
Imagen
- En la página de configuración
- Seleccione la red WiFi en la parte superior pulsando la que corresponda y después ingrese la contraseña en Password.
- ingrese los datos para "suplaServer (svrX.supla.org), Email(Email de registro en supla) y Supla Device Name (nombre con el que se verá en la nube)"
- Para terminar pulse en Save para guardar los datos de configuración.
