It was once the dishwasher, a rediscovered technology which has changed the lives of many, saving a lot of effort and time, then it was the turn of an era in which not even the convenience of an appliance like the dishwasher can be sufficient to satisfy a home or a housewife distracted.
Have you ever to forget it to empty the dishwasher and do not remember if there are dishes in clean, or dirty?
In any case, for those who could not perform this simple test, there is always the possibility of replicating the device created by this home-distracted-hacker. It is called Dish-O-Tron 6000 and unable to communicate if the dishwasher has its duty or if the dishes are still dirty that contains.
In practice the device understands by controlling the temperature of the dishwasher, if it was in operation, is also able to say whether the same has been cleared, or if it was opened only to take two clean dishes and so on (if the dishwasher door is completely open for more than a minute, means that has been emptied, otherwise no and the dishes inside, although fewer in number, are clean!).
