Digital twins play an important role in the Internet of Things (IoT). A digital twin represents data in a 3D view, which means it represents the data which contains some information. Both are dependent on each other, the digital twin visualizes or operates through IoT protocols, while through the digital twin it is possible to present the data of IoT in 3D form.
There are some applications where data these type of data comes from IoT devices through various channels and after preprocessing or filters the data in digital form used for visualization, hence IoT devices play a major role without IoT devices Digital Twin is possible but the application should be different.
