A smart device, as the name suggests, is an electronic gadget that is able to connect, share and interact with its user and other smart devices. Although usually small in size, smart devices typically have the computing power of a few gigabytes.
How Smart Homes Work
A smart home’s devices are connected with each other and can be accessed through one central point—a smartphone, tablet, laptop, or game console. Door locks, televisions, thermostats, home monitors, cameras, lights, and even appliances such as the refrigerator can be controlled through one home automation system. The system is installed on a mobile or other networked device, and the user can create time schedules for certain changes to take effect.
Smart home appliances come with self-learning skills so they can learn the homeowner’s schedules and make adjustments as needed. Smart homes enabled with lighting control allow homeowners to reduce electricity use and benefit from energy-related cost savings. Some home automation systems alert the homeowner if any motion is detected in the home when they’re away, while others can call the authorities—police or the fire department—in case of imminent situations. Once connected, services such as a smart doorbell, smart security system, and smart appliances are all part of the internet of things (IoT) technology, a network of physical objects that can gather and share electronic information.
Connectivity refers to the ability of a smart device to connect to a data network. Without connectivity, there is no point in a smart device being autonomous and having context-awareness. Network connectivity is a crucial feature which enables a device to be a part of the Internet of Things. Network connectivity can be wired or wireless.
