IoT devices can either be a sensor, antenna, or microcontroller, depending on the received data and information processed. The type of hardware used will, in turn, influence other factors such as the speed or cost or the type of connectivity. The usage of a device featuring the Internet of Things should always be such that it consumes low power for computation, requires low maintenance cost, and is preferably wireless. Device management is all about setting up the IoT device, maintaining it, and monitoring and evaluating it for any updates or errors.
