Internet of Things (IoT) devices contribute to smart homes by providing interconnected systems that improve convenience, efficiency, and security. Devices such as smart thermostats, lights, and security cameras communicate with each other and users via the internet. This interconnectivity allows homeowners to remotely control their environments, optimize energy usage, and enhance safety through real-time monitoring. Moreover, IoT devices can learn user behavior and preferences, enabling functionalities like automated lighting and climate control. This seamless integration of technology elevates the living experience, offering both comfort and peace of mind to residents.
