The WeatherBoard IoT module demonstration

The system captures data obtained by the capacitive moisture sensor and then sends it to the LCD for local display and then to thingspeak for remote display.

Este canal va a servir para poder realizar la practica de conectarme a la nuber y poder pasar la materia.
