We must first understand what a smart home is. Will you connect all the electrical appliances? Connect large and small appliances in your home. Design them into an APP in your mobile phone. Is it through some AI voice to issue instructions? Let it open, close, turn on the TV and turn off the TV. Are they some "useless" intelligent products? These products have linkage errors due to network outages?

Good smart home can bring us a very comfortable experience. A bad one will bring endless torture. The ideal life advertised in TV advertisements attracts us. Who of us doesn't want to have such an intelligent life? For example, maybe you go to the toilet at night. The lighting equipment can turn on automatically. It will not be too bright to irritate the eyes. In winter and summer, you can use the air conditioner. It will keep the temperature constant. It needn't complicated temperature adjustment or remote control. When driving home, the garage door can open automatically, etc.

With the release of communication protocol X10 for home automation in 1975, smart homes began to be realized. X10 sends 120 kHz radio frequency (RF) bursts of digital information to existing wires in the house, using programmable sockets or switches. These signals transmit commands to the corresponding equipment to control the operation mode and time of the equipment. For example, the transmitter can send a signal along the wires of the house to tell the equipment to turn on at a specific time.

The X10 is not always completely reliable because the design of electrical wiring does not specifically eliminate the "noise" in the radio frequency band. The signal will be lost. And in some cases, signals will not pass-through circuits wired with different polarities. X10 was originally a one-way technology. So, although smart devices can execute commands, they cannot send data back to the central network. However, two X10 devices came out later, although the cost was higher.

Nowadays, smart homes have become very popular. Such as smart door locks. When you go out, you don't need to bring any keys. The door card only needs our fingerprints to unlock the lock.

Sweeping robots are also one of the products of today's fire. When we go to work, the sweeping robot can sweep the floor at home alone. When the power supply is insufficient, you can charge yourself at the charging position.

Intelligent switch is also a good product. Most of these switches are embedded. It was already embedded in the wall when it was decorated. This switch supports many custom settings. A switch performs much more operations than a normal switch.

Of course, electric curtains have to be mentioned. Electric curtains are absolutely necessary for lazy people. When it is not remotely controlled, it is no different from an ordinary window, that is, an ordinary track curtain. But you can use your mobile phone or remote control to control it at any time. It is convenient to watch videos.

Smart homes are gradually changing our lives. Our life will also become more and more colorful because of smart home.
