1. Instrucciones en Arduino IDE<\/h4>\n

Para facilitar la programaci\u00f3n, se separan en funciones las acciones para enviar y recibir mensajes Lora y las de manejo de sensor\/actuador.<\/p>\n

El sensor DTH-11 se conecta al pin 13<\/p>\n

El sensor de bateria se conecta al pin 36 como entrada anal\u00f3gica.<\/p>\n
