How is the Internet of Things organized?

IoT devices function on their own, although people can configure them or provide access to data. IoT systems operate in real time and usually consist of a network of smart devices and a cloud platform to which they are connected using WiFi, Bluetooth, or other forms of communication.

What happens when the temperature is too high or there is a burglar in the house? The system notifies the user about this or performs further actions itself - for example, turns on the air conditioner or calls the police.
