• Asegúrate de definir los valores de umbral adecuados como THRESHOLD_ORGANIC y COLOR_THRESHOLD_RECYCLABLE para tu aplicación, dependiendo de cómo midas gases y colores.
• Asegúrate de probar y ajustar los tiempos de activación de los motores para tus puertas.
• Considera calibrar los sensores en un entorno controlado antes de poner en marcha el sistema.
