The history of IoT sensing technology can be traced back to the 1990s, when Xerox launched a network Coke vending machine, which is considered to be the earliest practice of the Internet of Things. In 1999, MIT professor Kevin Ashton proposed the concept of "Internet of Things", which refers to the establishment of a global information sharing "Internet of Things" using radio frequency identification (RFID), coding and Internet technologies.
IoT sensing technology refers to the technology that uses various sensors, communication technologies and data processing technologies to realize the perception, identification and understanding of the physical world. IoT sensing technology is the foundation and core of the Internet of Things, and it is also an important support for the new generation of information technologies such as artificial intelligence, big data, and cloud computing.
IoT sensing technology has undergone a transformation from digitalization to intelligence, from traditional wired connection to wireless connection, from a single sensor to the fusion of multiple sensors, from simple data collection to complex data analysis and decision-making. IoT sensing technology has a wide range of applications and prospects in smart cities, industrial Internet of Things, Internet of Vehicles, medical health, agricultural environment and other fields.
IoT perception technology is developing rapidly. The Intelligent Perception Networking Platform (AIOT PNP) is a fully connected and multi-field intelligent IoT basic support platform, providing cross-departmental and cross-business IoT perception and networking services for various industry scenarios. It realizes global perception, resource sharing, overall management, and collaborative management for various industry scenarios, provides one-stop IoT solutions, and facilitates IoT application innovation.
In the construction of the traditional urban IoT sensing network, it faces challenges such as fragmentation, high construction costs, difficulty in networking multi-source heterogeneous terminals, difficulty in data collection, security issues and complex management. However, new technologies such as IPv6+ and Hongmeng OS can provide network slicing, automation and security capabilities, enabling the interconnection of everything and cross-domain interoperability. These technologies can adapt to terminals of different types and resources, and the characteristics of distributed soft bus can fundamentally solve the problem of data intercommunication, and are the preferred carrier for intelligent terminals and data sharing.

What are the development trends of IoT perception technology in the future?
Intelligence: Sensors will have the functions of data collection, conversion, analysis and even decision-making, realize intelligent dialogue with people and things, and improve accuracy, reliability and adaptability.
Miniaturization: Sensors will use microelectromechanical systems (MEMS), complementary metal oxide semiconductors (CMOS) and other technologies to achieve low-cost mass production, reduce power consumption and volume, and achieve monolithic or heterogeneous integration.
Biomimetic: The sensor will learn from the biological structure and function of nature, realize sensitive response and adaptive adjustment to complex environments, and improve sensitivity, selectivity and stability.
Multi-spectralization: The sensor will use spectroscopy technology to analyze the physical and chemical properties of the material by measuring the spectral characteristics of the interaction between light and matter, so as to achieve accurate measurement of solid, liquid and even gaseous items.
