In a university in Shanghai, a science and engineering man changed the lock of the dormitory into a smart lock and saw the netizen for a while. This smart lock is very different from the smart lock on the market, at least it looks like a semi-finished product. But it has many functions, such as fingerprint unlocking, voice-activated unlocking, and even unlocking through the APP. Some netizens say that science and engineering boys are very powerful. The smart lock that everyone spent thousands of dollars on may not support voice control, but it took him a week to make it. Then someone asked, why did he do it? First of all, it should be his hobby, so he likes to do it. Secondly, this is to test your knowledge. Finally, it is also to facilitate the daily opening and closing of the door. Next, let's take a concrete look.

First, it should be his hobby, so he likes to do it. If it is not his hobby, it is estimated that it is difficult for someone to have the perseverance to complete the production of this smart lock. Some parts of this smart lock were taken in the laboratory and some were bought online. The manufacturing process should be more complicated and more difficult. So it is very likely that this smart lock was invented because this boy likes to do it.

Second, it is a test of your knowledge. The production of this smart lock involves a lot of knowledge. Maybe this tech guy made this smart lock to test his knowledge. After all, it is meaningful to apply what you have learned in real life.

Third, it is also to facilitate the daily opening and closing of the door. With this smart lock, you can not only open the door by fingerprint, but also control it by voice. You can also use the APP to open the door, which is convenient to think about. So making this smart lock should also be for the convenience of life. Otherwise, why not do something else but make a smart lock?

So, this boy made this smart lock. In my opinion, this kind of lock can fully meet the daily needs. Do you have any different opinions? Welcome to discuss.
