Smart devices, also called smart technologies or smart tools, are everyday “things” that have been embedded with sensors and microprocessors to collect data, perform automated processing, and adapt their behavior on the basis of the gathered information. They are a key part of the Internet of Things (IoT) paradigm, and they embody the growing penetration of information technology into daily life.
A smart device’s sensor is a system that detects and measures its environment, like temperature or light levels. It sends this information to a processor, which often uses artificial intelligence or a built-in application for this purpose. The processor then decides to act, like adjusting the thermostat or turning on a light. In addition, some smart devices have actuators that can be activated manually, or in response to user commands.
Many smart devices connect to ecosystems or companion apps that allow them to communicate and control other connected products. This enables users to create a single, integrated system that automatically turns lights on and off or runs a routine based on your schedule. Examples of such systems include smart speakers, smart displays and home security systems.
When selecting smart devices, you should always consider the privacy implications of the data they produce or share. If you are considering buying a smart doorbell or baby monitor, for example, you should be aware that they may track your movements and record your conversations. They can also transmit private data, such as passwords and personal identification numbers.
