Activity 4
A smart home is one that integrates computers into the structure of the building itself. In this way, many of the things that we now do ourselves will become automatic. For example, the smart home could control the air conditioning and lights so that you would no longer have to turn switches on or off, making your home more energy–efficient. The smart home could also monitor itself to make sure that everything is working as it should, and send you warnings if there is a problem. Such smart homes could even be programmed to detect your health problems, and then give you relevant advice as to the food you should eat or if you should see a doctor. So, in a sense, smart homes will lead us to living smarter lives.
