An MQTT client is any device (from a microcontroller up to a full-fledged server) that runs an MQTT library and connects to an MQTT broker over a network. [18] Information is organized in a hierarchy of topics. When a publisher has a new item of data to distribute, it sends a control message with the data to the connected broker.
MQTT is an ISO standard (ISO/IEC PRF 20922) [1] publish–subscribe-based messaging protocol.It works on top of the Internet protocol suite TCP/IP. It is designed for connections with remote locations where a "small code footprint" is required or the network bandwidth is limited.
Smart manufacturing [1] is a broad category of manufacturing that employs computer-integrated manufacturing, high levels of adaptability and rapid design changes, digital information technology, and more flexible technical workforce training. [2]

S.M.A.R.T. (or SMART) is an acronym used as a mnemonic device to establish criteria for effective goal-setting and objective development. This framework is commonly applied in various fields, including project management, employee performance management, and personal development.
Structure of the TOGAF Architecture Development Method (ADM). [1]The Open Group Architecture Framework (TOGAF) is the most used framework for enterprise architecture as of 2020 [2] that provides an approach for designing, planning, implementing, and governing an enterprise information technology architecture.

Surface-mount technology was developed in the 1960s. By 1986, surface-mounted components accounted for 10% of the market at most but were rapidly gaining popularity. [4] By the late 1990s, the great majority of high-tech electronic printed circuit assemblies were dominated by surface mount devices.
The modules are deployed together with an application-specific carrier board, whose size and form can be defined to meet customer-specific requirements. The carrier board executes the required interfaces and can integrate, if required, any further functionalities, such as audio codecs, touch controller, wireless communication interfaces, etc.
