Internet of Things is a new rvolutionary technology where electronic devices are connected wirelessly either to a smartphone/tablet or to the cloud/remote server. The device measures data with the help of its sensors and transfers it to the connected smartphone/tablet or cloud for further processing of the data or control actions if required. The data sent can be then analyzed using intelligent algorithms for actionable insights.
IoT devices, or any of the numerous things floating in the internet of things, are nonstandard computing devices which connect wirelessly to a network and can transmit data.
These devices can communicate via the internet and can be remotely monitored and controlled as they are Embedded with technology.
IoT technology stack and start with three layers. The first layer is the IoT device level; as without accurate sensors, actuators and IoT devices, there will be no accurate data and without which no Internet of Things, leaving aside all the IoT projects or products/services. Second layer is the IoT gateway, which deserves a spot as a layer and certainly in an overview of the IoT device layer with which it is strongly connected and for which is an important level towards the next steps of usable data and business applications or consumer applications and services. The third layer is the IoT platform layer where the actual connection with the business and consumer applications and services, as well as the development of these services and the management and interconnection with the first two layers takes place.
IoT bridges the gap between the physical world and the digital world and that starts with things. There are a number of IoT devices in a broader sense, some sit at the edge of the network where actual connecting of things happens. The others include IoT gateways which allow to actually work with all the data coming from ‘IoT-enabled’ things or connected products. However, we won’t count IoT gateways as IoT devices as some people do, it’s a completely different IoT technology layer and not even necessarily hardware.
