IoT is an important part of the new generation of information technology.

The core and foundation of IoT is the Internet. Through the extension and expansion of the Internet, with the help of radio frequency identification,iot modules infrared sensors, global positioning systems, laser scanners and other information sensing devices, information exchange and communication between items is realized in accordance with the agreed protocols, so as to carry out intelligent identification, positioning, tracking, monitoring and management of items.

The Internet of Things is the fusion of intelligent sensing, recognition system technology and pervasive computing, ubiquitous network of convergence of educational applications,5g fwa and is therefore known as the third wave of the world's economic information to carry out the continuous development of the industry following the computer, the Internet enterprise.

It has the following three characteristics:

Overall perception, the use of radio frequency identification (RFID), two-dimensional code (QR), intelligent sensors and other sensing devices, you can obtain a variety of information about the object.

Reliable transmission, real-time and accurate transmission of goods information through network integration to realize information exchange and sharing.

Intelligent processing, with the help of intelligent technology, the received data and information are analyzed and processed to realize intelligent monitoring.

The application field of IoT involves all aspects. Its application in the fields of industry, agriculture, environment, transportation, logistics, security and other infrastructures effectively promotes the intelligent development of these aspects, resulting in a more effective distribution of resources and a more efficient life.

Common application scenarios of IoT technology in our daily learning life are:

Smart home, through IoT technology, we can remotely control smart air conditioning and adjust the temperature through mobile applets, and if you buy a smart scale, the system will automatically monitor your health and synchronize it to your phone. There is also smart lighting control, motorized curtain control and intercom access

Smart transportation, the automatic toll collection system implemented at highway intersections is an application of IoT technology. As long as the vehicle information is linked to the bank information, there is no need to run a card when coming and going, and the fee is automatically deducted; the traffic monitoring function can quickly communicate the road information collected on the network to the driver in a timely manner to avoid congestion; if you go out and can't find a parking space, you can check the sharing software and quickly settle your car.

Public safety, IoT technology is also widely used in public safety, air defense, traffic safety, fire safety and other urban security areas, through advanced sensing technology to help civil servants accurately locate the location of suspects, to ensure capture; the installation of IoT sensors in the city, to monitor the infrastructure of buildings, roads, bridges, etc., to prevent disasters and reduce the threat to human life and property.

There are many application scenarios of IoT, such as shared charging treasure, smart massage chair, smart vending machine, smart door locks and so on. The rapid development of IoT and many application scenarios are unimaginable in the past. By the time we realize it, IoT technology has become an integral part of our lives. With the arrival of the 5G era, the demand for the development of IoT will become more and more vigorous, and the combined application of IoT and small programs will make our lives better.
