The perception layer is the layer of the Internet of Things architecture.

The perception layer is the first layer of the Internet of Things architecture. The perception layer is composed of various sensors and sensor gateway architecture technical architecture diagrams, including carbon dioxide concentration sensors, temperature sensors, humidity sensors, QR code tags, RFID tags and readers, cameras, GPS and other sensing terminals.

The perception layer is the first layer of the Internet of Things architecture

1. From the perspective of technical architecture, the Internet of Things can be divided into three layers: perception layer, network layer and application layer.

2. The perception layer is composed of various sensors and sensor gateway architecture technology architecture diagrams, including carbon dioxide concentration sensors, temperature sensors, humidity sensors, QR code tags, RFID tags and readers, cameras, and GPS Wait for the sensing terminal. The role of the perception layer is equivalent to the nerve endings of human eyes, ears, nose, throat and skin. It is the source of identifying objects and collecting information for the Internet of Things. Its main function is to identify objects and collect information.

3. The network layer consists of various private networks, the Internet, wired and wireless communication networks, network management systems and cloud computing platforms. It is equivalent to the human nerve center and brain and is responsible for transmitting and processing the perceptual layer acquisition. Information.

4. The application layer is the interface between the Internet of Things and users (including people, organizations and other systems). It is combined with industry needs to realize intelligent applications of the Internet of Things.

Extended information:

1. The Internet of Things is the Internet where things are connected. This has two meanings:

(1) The core and foundation of the Internet of Things is still the Internet, which is an extended and expanded network based on the Internet.

(2) Its user terminal extends and expands to any item and item for information exchange and communication, that is, things are related to each other. The Internet of Things is widely used in the integration of networks through communication sensing technologies such as intelligent sensing, identification technology and ubiquitous computing. It is therefore known as the third wave of the development of the world's information industry after computers and the Internet.

2. Use communication technologies such as local networks or the Internet to connect sensors, controllers, machines, people and things in new ways to form connections between people and things, things and things, and realize informatization. , remote management control and intelligent network. The Internet of Things is an extension of the Internet. It includes the Internet and all resources on the Internet, and is compatible with all Internet applications. However, all elements in the Internet of Things (all devices, resources, communications, etc.) are personalized and privatized.
