IoT Devices are programmable boards and nonstandard computing devices that have the ability to transmit data over the network.
They have a unique identity and are referred to as “things” in IoT. Devices can perform identification, remote sensing, actuating and monitoring.
They can exchange data between them and process data or send them to a centralized location for processing and storage.
They provide an interface to various wired and wireless devices. The interface includes memory interface, I/O interface for sensors, Internet connectivity interface, storage interface, etc.
These Devices are mainly part of projects like home automation, smart parking, lighting, security systems, etc.
