The internet of things is simply: the connection between people and things, things and things. When these connections can access the Internet, it is the Internet of Things. For example, you have a bracelet that can monitor blood sugar, blood lipid and blood pressure. If the monitored data is not connected to the Internet, it is just a monitor. Once these data are connected to the Internet, you can analyze and evaluate your health, which becomes a part of the Internet of Things. For another example, the air conditioner can automatically adjust the wind according to the temperature. If there is no internet connection, it is just the automatic mode of air conditioning. If the data monitored by the air conditioner is networked, it will be broadcast to you through the smart speaker or send a message to your mobile phone. This is the Internet of Things.
I hope these can help you.
