This is called Internet of Things. The Internet of things (IoT) is a system of interrelated computing devices like vehicles, and other items embedded with electronics, software, sensors, actuators, and network connectivity with unique identifiers which enable these objects to collect and exchange data over a network without requiring human-to-human or human-to-computer interaction.

Logical Data Model
Explanation:
An Entity Relationship Diagram (ERD) is a model or a diagram designed to reveal the relationship between various entities such as people, places, objects, and so on within an institution. Entity relationship diagram is also known as Entity relationship model. This model is used to design relational database by various sectors such as education, engineering, business, etc.
<u>ERD is designed using conceptual data model, logical data model, and physical data model</u>.
The visual practice or model that gives more insight into the logical relations among the entity is the logical data model.
The logical data model is used to illustrate more detailed operational and relational data among the entities. It is more detailed than the conceptual data.
So, the correct answer is logical data model.
