When you see “I am a sentence I am another sentence,” you know that you’re really looking at two different sentences even though the period between “sentence” and “I” is missing.Even when we’re not here, the room is drawing a lot of power.What devices are turned on at any given time depends largely on which of us is here, and what we’re doing.
This project is a system to reduce our power consumption, particularly when we’re not there.When either of us comes into the room, all we have to do is tap our key fobs on a reader mounted by the door, and the room turns on or off what we normally use. The reader by the door reads the presence or absence of the tags.
