The Internet of Things (IoT) is one of the most popular technological terms in recent years. In simple terms, IoT refers to the use of information sensing devices such as radio frequency identification, infrared sensing, positioning systems, and scanning to connect any object to the Internet in accordance with established protocols for message interaction and communication. A network for intelligent identification, positioning, monitoring, and management of objects. It has been widely used as a representative in four major fields: medical treatment, transportation, logistics, and life.
