What are the main technologies of the Internet of Things?

The three key technologies and fields of the Internet of Things include key technologies: sensor technology, RFID tag and embedded system technology. Fields: public affairs management (energy saving and environmental protection, traffic management, etc. ), public social services (medical health, housing construction, financial insurance, etc. ), economic development and construction (energy and electricity, logistics and retail, etc.). ).

The concept of "Internet of Things" was put forward in 1999, and its definition is simple: all items are connected to the Internet through information sensing devices such as radio frequency identification, so as to realize intelligent identification and management. In other words, the Internet of Things refers to the new technology of connecting various sensors with the existing Internet.

In 2005, the International Telecommunication Union (ITU) published "ITU Internet Report 2005 Internet of Things", pointing out that the ubiquitous "Internet of Things" communication era is coming, and all objects in the world, from tires to toothbrushes, from houses to paper towels, can be actively exchanged through the Internet. Radio frequency identification technology (RFID), sensor technology, nanotechnology and intelligent embedding technology will be more widely used.

In March 2008, the world's first international conference on the Internet of Things "Internet of Things 2008" was held in Zurich. The conference discussed the new concepts and technologies of the Internet of Things and how to push it to the next development stage.
