Arduino UV-C Sterilization Control

1:35

Aquí tienes una versión modificada del código donde se reemplaza el interruptor de mercurio por un sensor magnético para puertas. He realizado los siguientes cambios:
  • Renombré la variable mercurySwitchPin a doorSensorPin.
  • Renombré las variables relacionadas (mercurySwitchState y lastMercurySwitchState) a doorSensorState y lastDoorSensorState.
  • Se actualizan los comentarios para reflejar que se usa un sensor magnético de puerta.
Puedes revisar el siguiente código:
