How Sensors Improve Your Life
To make your home smarter, "sensors" are the very important components. With sensors installed, you can do a lot of automation.
You can automatically off all the electrical appliances when you not at home. Or smart the air-condition 5 mins before you back home. Or auto turn on the restroom light when you enter the restroom at night.
It is amazing, funny, interesting and awesome. What do you think?
