However, you might as well think about it, have we really used these technologies in our work, life, and even industrial development? Let's talk about our lives first! Among home appliances, the most commonly used example for the Internet of Things is the refrigerator. If you are working remotely from home, you might as well look back at your refrigerator. Is it an intelligent IoT device? If not, why? If yes, are you satisfied? A few years ago, some home appliance manufacturers installed a refrigerator on a tablet computer, thinking that this is a smart IoT home appliance, but apparently they did not convince the public.
The Internet of Things is not just about connecting everything to the Internet, let alone installing hundreds of sensors In fact, the ability of a device to connect to the Internet cannot be directly equated with whether it is smart enough. If a refrigerator can be connected whatsapp list to the Internet, but the user has to judge for himself which items are expired and which items should be placed in an e-commerce order... Honestly, that doesn't change much, does it? Therefore, a truly "smart" refrigerator can't just be connected to the Internet. It has to be equipped with a lot of sensors, such as weight sensors to determine how much milk you drink in a bottle, and visual sensors to determine when it expires.
The taste sensor determines that the food is not expired but has been spoiled, and even the sensor that records how many times a day is turned on and off to help monitor the diet of diabetic patients. These technologies are not difficult, but they are just the beginning. The Internet of Things has never just been connected to the Internet, but also more sensors to provide information! So why is the concept of IoT immature? That's because the Internet connection is not enough, and more data needs to be sent, but more data does not really solve the problem, and when the "problem" is not clearly defined, it causes trouble.
