With the development of science and technology, more and more changes have appeared in our society and lives. If you look closely, you'll find that our world is getting smarter all the time. A smart home is controlled by a group of connected devices(设备). These devices work together to control things like security(安全), temperature and entertain- ment(娱乐).
The smart security system makes it easier to see each other and communicate through home cameras from anywhere. Have you ever locked your keys inside your home? Not a problem! The smart security system can lock or unlock the front door without a key.
When it's cold outside, most people want their homes to be warm. A smart temperature controller will remember what time people arrive home every day and make sure it's nice and warm when they walk in.
Smart speakers also make homes smarter. They listen for a special word or phrase and then follow the order that is given to them. A smart speaker might respond to "Please play my favorite music" or "Remind me to finish my homework later'.
Living in a smart home sounds cool, doesn't it? As time goes on, we're sure to find more ways to make our homes smarter!
