Smart devices are electronic devices that can connect to the internet and perform tasks independently or in response to commands. They often have built-in sensors and software that allow them to collect data, process information, and interact with their environment. A smart device is often characterised by its ability to be controlled via an app or online account. Smart devices are an essential element which contributes to home automation. Examples of smart devices include TVs, fridges, washing machines, ovens and security cameras.
