various APIs, smart devices, and online services To put it in other words, NodeRED is a flow-based development engine that groups together various visual flows using simple and intuitive editing services accessible from a web browser Used to create JavaScript functions, it stores the created flows in the open-standard and widely used JSON file format which makes it possible to easily re-use or share them freely a commercial solution sold under the name BeagleBone (Avsystem, 2021) f RIOT Figure 24: Riot tool P a g e | 32 0 RIOT focuses on low-power memory-constrained smart devices to bring a solution that supports 32-bit, 16-bit, and 8-bit microcontroller architectures Functioning as an alternative to Linux, RIOT is a microkernel operating system supporting multiple chip architectures that supports 6LoWPAN, IPv6, RPL, and UDP Providing very minimal processing, power, and memory usage, this open-source IoT tool is best suited to systems of low-power microcontrollers and networks of small sensors (Avsystem, 2021) g DeviceHub Figure 25: DeviceHub tool Considered to be one of the most crucial open-source IoT tools, DeviceHub.net offers a cloud solution for tracking, monitoring and controlling devices The data it collects is accessible directly from the webpage and in real time, therefore its most popular use cases include the ones in which instant and unobstructed access to data is of highest priority: ranging from health care monitoring, through vehicle and movable asset location, to gathering weather telemetry data, etc (Avsystem, 2021) P a g e | 33 0 h The Thing System Figure 26: The Thing System The Thing System is a set of software components and network protocols promising to discover and get together all the Internet-connected home-based gear to offer its users full control over their smart assets The list of supported smart devices is impressively long and includes, among others, air conditioners, LED bulbs, Nest thermostats, Google Chromecast, IoT-enabled locks and many, many more (Avsystem, 2021) i Anjay Figure 27: Deploying Anjay for Raspberry Pi P a g e | 34 0 Anjay is a Software Development Kit (SDK) developed by AVSystem that leverages the Lightweight M2M protocol to offer probably the most complete LwM2M library to be found in the industry to date, acting de facto as a global reference implementation for IoT tools providers as well as device manufacturers Anjay is designed to integrate seamlessly with resource-constrained devices while offering minimal RAM, Flash and CPU usage As a fully open-source solution, the Anjay software and documentation is freely available on GitHub To those in need for a more commercial approach, AVSystem provides vast support for Anjay together with access to a test server of their Coiote IoT Device Management platform, additional APIs and SMS binding (Avsystem, 2021) According to the company, Anjay9s contribution to developing and maintaining IoT standards will be a significant step towards the global adaptation of the LwM2M protocol across the industry, and will help to bridge the two major gaps that haunt the presence and the future of the Internet of Things: security and interoperability In a world that needs multi-million device deployments to make our lives smarter, standards-based implementations are key for manufacturers, service providers and end customers alike (Avsystem, 2021) k Key takeaways Figure 28: Key takeaways environment Just as the Internet of Things is an extremely varied and lively environment to build your business in, there are no off-the-shelf solution sets to cater for every smart project While the open-source IoT tools presented above constitute the potential building blocks for practically any smart system, it has to P a g e | 35 0 be borne in mind that some may perform successfully in some environments, but others may not be the best fit for the scope or scale of specific architectures or use cases (Avsystem, 2021) To put it simply, there are no silver-bullet solutions among the IoT tools offered for free usage; nevertheless, without the open-source IoT tools to accelerate the innovation and availability, the Internet of Things wouldn9t be able to evolve and reach the prominent place it occupies now in the IT industry It is therefore evident that open-source IoT tools may be not only a great starting point for your smart enterprise, but a cornerstone as in some cases open-source technologies may outrun their proprietary counterparts Plus, as your business develops, you can always switch to commercial technologies since open source most often means that you9re not tied to any specific vendor (Avsystem, 2021) 3.3 Conclusion – IoT Tools We have seen some tools of IoT in this article but there are many more significant ones available These tools help the developers to explore and create innovative IoT applications and devices These tools can help you to pursue your career in IoT and contribute to the IoT development society IoT Hardware 4.1 Introduction to IoT Hardware Figure 29: Overview IoT hardware On the Internet of Things, hardware comes in many forms, whether the underlying processors control the phones, the sensors collecting information from the physical world, or the edge machines processing and analyzing the data At the heart of any wired venture is IoT hardware and the technical P a g e | 36 0 capabilities of these boards have only become more important as the Internet of Things has developed But, because of the sheer number of design boards and modules in the room, choosing the right IoT hardware for a project can be daunting In this article, we will look at different aspects of IoT hardware and see how these devices communicate data to the internet (Educba, 2021) 4.2 Common IoT Hardware Devices The building blocks of an IoT device are remarkably similar, whether undertaking projects related to the wearable device, an integrated lighting system, or even a jet engine Wireless sensor node consists of three major hardware components they are sensors, microcontrollers, and communication medium (Educba, 2021) a Sensors in IoT Figure 30: IoT sensors Sensors are the most critical hardware in IoT applications and are used to gather information from the surroundings These systems are made up of power management modules, RF, energy and sensing modules Communication from Wi-Fi, Bluetooth, transceiver, BAW, and duplexer is managed by an RF module The figure above is about sensors of Arduino (Educba, 2021) P a g e | 37 0 b Microcontrollers Figure 31: Microcontroller A microcontroller is a device in a single integrated circuit devoted to executing a single task and running an application This contains programmable peripherals for contains programmable, memory unit, and a CPU Microcontrollers are designed primarily for embedded applications and are widely used in remotely operated electronic devices such as mobile phones, washing machines, microwaves, and cameras (Educba, 2021) c Other IoT hardware in special field Smart wearable devices such as smart memory, glasses, rings, and shoes are examples of IoT hardware Smart devices allow us to access more of the content and resources that we love and create a new approach to collaboration as part of an IoT network Desktop, mobile phones, and tablets are standard command center and remains an integral part of IoT application Other network distribution devices like switches, hubs, and routers act as a key connector in IoT application (Educba, 2021) 4.3 Conclusion In this article, we have looked at different building blocks of IoT devices The hardware component is the most important part of the IoT application that enables things to communicate with the Internet We have further looked at a few of the IoT hardware providers in today9s market and evaluated them individually (Educba, 2021) P a g e | 38 0 IoT APIs 5.1 What is an IoT API?
