What is the Internet of Things? It can be understood as the internet that connects everything.
To realize the functions of the Internet of Things, it still relies on the internet as the foundation and core, enabling information exchange and communication between objects. The application fields of the Internet of Things mainly include: transportation and logistics, industrial manufacturing, health care, smart homes, smart agriculture, and self-service retail. The information collection devices of the Internet of Things mainly include: RFID, sensors, infrared, GPS positioning, etc.
History of the Internet of Things
A programmer at Carnegie Mellon University connected a Coca-Cola vending machine to the internet, allowing engineers to know how many Cokes were left without going downstairs. This can be considered one of the earliest Internet of Things devices.
In response to a challenge, John Romkey connected a toaster to the internet and successfully turned it on and off, bringing us closer to what we consider modern Internet of Things devices.
Scientists at the Cambridge University Trojan Computer Lab often had to go downstairs to check if the coffee was ready. To solve this problem, they installed a portable camera next to the coffee pot, using terminal computer image capture technology to transmit images to the lab’s computer at a rate of 3 frames per second, allowing staff to check if the coffee was ready. This is a typical early prototype of the Internet of Things.
The first version of the GPS satellite program operated by the US government was finally completed, allowing many Internet of Things devices to provide one of the most important functions: location.
Bill Gates mentioned the concept of the Internet of Things in his book
