Incorporar Antena LoRa en Código

1:09

Aquí tienes el código modificado para incluir el envío de datos vía LoRa. He agregado la biblioteca LoRa y configurado algunos pines (ajústalos según tu hardware). Se arma un mensaje CSV con las variables medidas y se transmite vía LoRa en cada ciclo. Puedes ajustar la frecuencia y los pines a tus necesidades.
