Smart appliances are household devices that connect to the internet and can be controlled remotely through smartphones or other devices. They often use sensors and artificial intelligence to enhance their functionality, making tasks easier and more efficient. Examples include smart refrigerators that can track food inventory and smart ovens that can be preheated from a distance. These appliances can also communicate with each other, creating a more integrated home environment. For instance, a smart washing machine can notify you when a cycle is complete, while a smart thermostat can adjust the temperature based on your preferences. This connectivity helps save energy and improve convenience.
