internet of things, or IoT, is a network of connected computing devices, mechanical and digital machinery, items, animals, or people that are provided with unique identifiers (UIDs) that may exchange data across a network without requiring human-to-human or human-to-computer interaction These gadgets include anything from common domestic items to high-tech industrial gear Today, there are more than billion connected IoT devices, and according to analysts, there will be 10 billion by 2020 and 22 billion by 2025 The term "thing" refers to any natural or artificial object that can be given an Internet Protocol (IP) address and could transfer data over a network, including people with implanted heart monitors, farm animals with biochip transponders, cars with built-in tire pressure monitors, and other examples Organizations across a range of industries are increasingly utilizing IoT to run more smoothly, better understand their consumers to provide better customer service, boost decision-making, and raise the value of the company 2/ How does IoT work? The Internet of Things (IoT) ecosystem is made up of web-enabled smart devices that use embedded systems, such as processors, sensors, and communication gear, to gather, send, and act on the data they get from their surroundings By connecting to an IoT gateway or other edge device, which either sends data to the cloud for analysis or analyzes it locally, IoT devices exchange the sensor data they collect These gadgets converse with other similar devices on occasion, acting on the data they exchange Although individuals can engage with the devices to set them up, give them instructions, or retrieve the data, the gadgets accomplish much of the job without their help These web-enabled devices' connectivity, networking, and communication protocols are heavily influenced by the IoT applications that have been implemented IoT can also employ machine learning and artificial intelligence (AI) to help make data collection processes simpler and more dynamic Page 3/ Applications of IoT Business-ready, SaaS IoT Applications IoT Intelligent Applications are prebuilt SaaS applications that can analyze and display IoT sensor data to corporate users via dashboards A whole range of IoT Intelligent Applications are available IoT apps analyze vast volumes of linked sensor data in the cloud using machine learning algorithms You may see important performance indicators, statistics for the mean time between failures, and other data using real-time IoT dashboards and alerts Algorithms built on machine learning can detect abnormalities in equipment, inform users, and even start automated repairs or preventative steps Business users may immediately improve current operations for supply chains, customer service, human resources, and financial services with cloud based IoT apps There is no need to start from scratch with every business procedure Page 4/ IoT characteristics There are the following characteristics of IoT as follows Let’s discuss it one by one • Connectivity Connectivity is an important requirement of the IoT infrastructure The IoT infrastructure should be connected to IoT objects This should always be guaranteed to be possible for everyone, everywhere, at any time For instance, connections between individuals via internet-connected devices like smartphones and other gadgets, as well as connections between individual Internet-connected objects like routers, gateways, sensors, etc • Intelligence and Identity It is crucial to extract knowledge from the generated data For instance, a sensor might produce data, but that information won't be helpful unless it is properly evaluated IoT devices each have a distinct identity The equipment can sometimes be tracked using this identity, and its condition can occasionally be inquired • Scalability The number of elements connected to the IoT zone is increasing day by day An IoT setup should therefore be able to handle the enormous expansion Because of how much data is produced as a result, it needs to be handled carefully • Dynamic and Self-Adapting (Complexity) IoT devices should dynamically adjust to the various scenarios and contexts Assume there is a camera for surveillance It should be flexible enough to operate in various lighting and environmental circumstances (morning, afternoon, night) • Architecture IoT architecture can't be uniform in design It must be hybrid and able to work with items from various manufacturers in the IoT network No engineering branch owns the Internet of Things When several disciplines join, IoT becomes a reality • Safety When a user's gadgets are all online, there is a risk that the user's sensitive personal information will be compromised The user may suffer a loss as a result Data security is the main issue as a result In addition, the necessary equipment is enormous IoT networks could also be under danger Safety of the equipment is therefore essential Some examples for real world application of IoT Page • Shopping Mall – Proximity Marketing The modern consumer loves the ease of a digital lens but also likes to feel and touch products before making a purchase As a result, when a customer who frequently visits a store is in close proximity to that store, IoT sensors can send the customer's information to the hyper decision framework, which will analyze the customer's behavior and shopping patterns to send the appropriate message to the appropriate person, at the appropriate time and place • Asset Tracking High-value inventory, tools, fixtures, dies, jigs and other items for the industry are examples of assets For the healthcare industry, examples of assets include numerous movable test machines like the ECG machine, portable X-ray machines, portable ultrasound machines, stretchers, and wheelchairs These assets must be tracked in order to make it simple to keep track of their location, and lifespan, and help with yearly asset audits BLE IoT sensors are used to connect assets Anyone who requires information about the asset can check the dashboard, application, or mobile device to see where it is because these sensors communicate with the receivers • Warehouse Pallet Tracking For many businesses, reusable pallets in a warehouse are a valuable resource Pallet tracking makes it simple to identify the location of the pallets and helps to prevent time and valuable inventory waste as warehouses grow in size and the variety of inventory expands every year Pallets may also be equipped with BLE IoT sensors, which can offer useful details on the pallet's position as well as the inventory and date it is holding • Employee Monitoring Monitoring employees on the organization's campus are crucial for security and morale-boosting reasons in addition to productivity-boosting purposes Employees can wear BLE IoT sensors in the form of ID cards These ID cards feature Internet of Things (IoT) sensors that can detect whether the card is on a person or not, allowing security to be handled and productivity to be tracked based on proximity to each machine or process • Temperature and Humidity Monitoring The application of IoT sensors in supply chain management for "Cold Chain" is greatest These sensors take temperature and humidity readings within the containers and relay the information along with the truck's GPS location The advantage over existing data recorders is that the IoT sensor can communicate with the Hyper Decision Framework and assist in real-time problem correction rather than fingerpointing and playing the blame game saving time, money, and reputation in the process • Security Patrol Guard Management Page When a terrorist attack occurs, security guards' primary problem is that they lack the means to contact their teammates and ask for assistance The security patrol guard must frequently choose between losing his weapon and his life How does the Internet of Things help in this situation? The BLE ID Card is carried by the security guard over his shoulder He can double-click the distress button on the card in the event of an attack The hyper decision framework engages to send the message to the closest available support when this SoS signal is sent in real-time to the IoT cloud server P2 Review standard architecture, frameworks, tools, hardware and APIs available for use in IoT development 1/ IOT architecture IoT architecture, in its simplest form, is a collection of components including sensors, protocols, actuators, cloud services, and layers IoT architecture has four stages due of its complexity This quantity is designed to gradually integrate these many types of components into an advanced and cohesive network Advantages: • • • • • • Make edge devices simpler and less expensive A gateway can serve as a hub for connecting wireless and various data standards Protocols that present a consistent exterior to the outer world Rather than having to interact with each component individually, things are simple to monitor and regulate as a whole Gateway can manage what information is transferred to the Internet and offer greater security than items Easy to integrate legacy equipment with the IoT Disadvantages • • • An additional "Tier" increases integration complexity Resources are still locally stored as opposed to accessing the cloud An additional point of failure 2/ IOT NETWORK SYSTEM ARCHITECTURE Page As you can see from the image above, the IoT architecture has layers: the sensor layer, the network layer, the data processing layer, and the application layer Sensor Layer Sensors, actuators, devices are included in this sensor class These sensors or actuators receive data (Physical/Environmental parameters), process the data, and transmit it over the network Network Layer Internet (network) gateways, data acquisition systems (DAS) appear in this layer The DAS performs the function of data aggregation and conversion (Collects data and aggregates data and then converts the sensor's analog data to digital data, ) Advanced ports mainly open the connection between Sensor networks and the Internet also perform many basic functions, such as anti-malware protection and filtering some decision-making based on entered data and data management services Data Processing Layer This is the processing unit of the IoT ecosystem Here, data is analyzed and processed before being sent to the data center, where the data is accessed by software applications commonly known as business applications This is where data is tracked and managed Other actions are also prepared in this class Page 10 To put it another way, a cloud application is the written implementation of an IoT framework that connects all of the local hardware devices and cloud-based gadgets 3/ List of IoT Framework Now we will discuss the IoT Framework one by one KAA IoT One of the best and most complete Open-Source Internet of Things Cloud Platforms is Kaa IoT, where

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 5/ IOT hardware IoT Hardware components can vary from IoT Low-power boards, single-board processors like the Arduino Uno, which are essentially tiny boards that be inserted into mainboards to improve and increase their functionality by bringing forth specific tasks or features, are just a few examples of the hardware components that can be used (such as GPS, light and heat sensors, or interactive displays) A programmer defines the inputs and outputs on a board before designing a circuit to show how these inputs and outputs interact The Raspberry Pi is a popular IoT platform that is a small, extremely affordable computer that can function as a complete web server It is frequently referred to as "RasPi," and it has sufficient processing and memory to run both IoT Core and Windows 10 on it RasPi has excellent processing power, particularly when Python is used as the programming language A single-board computer called Beagle Board uses an ARM processor, which is more powerful than RasPi's and runs a Linux-based operating system Galileo and Edison boards from tech giant Intel are further alternatives; both are excellent for larger-scale production, while Qualcomm has produced a variety of enterprise-level IoT technology for everything from automobiles and cameras to healthcare API in IOT Page 18 In general, the phrase "API" refers to the standard structure, protocols, and resources that govern the most common web and mobile applications It outlines the guidelines for communication that each application component must adhere to when transferring data IoT APIs are APIs that are utilized in the development of IoT systems They are the application programming interfaces for web services They operate similarly and enable smooth data flow using HTTP as the conduit Developers can create complex apps that are simple to combine with other web services by using the IoT API The end-user experience is enhanced by IoT APIs in a number of ways For instance, people can effortlessly access websites and upload a sizable number of programs API Types in IoT IoT APIs come in a wide variety to help IoT development in all ways The following list includes the main API types • SOAP As they simplify creating a communication link between the servers and the clients, SOAP APIs are essential for the creation of IoT devices The API only permits the transfer of data using XML • REST IoT REST APIs are beneficial for HTTP data transport and enabling IoT devices to remain connected to the outside world These APIs, which are based on architectural principles, have properties like easily manipulable interfaces, fast resource identification during requests, and interface simplification • JSON and XML Page 19 JSON and XML IoT APIs are a little more traditional than SOAP APIs and use a smaller amount of bandwidth The important role of APIs in the IoT The ability of APIs to effectively utilize pre-existing functionality to ensure smooth software processing while freeing developers from the need to repeatedly reprogram is what makes them essential for IoT and any other device/software The IoT world is too complicated, necessitating constant communication between the various actors engaged The operation can be completed using APIs because it is entirely feasible to integrate various IoT components with one another The IoT world is empowered by API usage, which creates countless new development and integration options IoT APIs are fantastic tools for technical development because they offer unrivaled flexibility Speaking of cybersecurity, APIs are crucial since they allow developers to take charge of access requests The possibility of a DDoS assault is kept to a minimum by this restricted and controlled access When all of this is considered, it's simple to draw the conclusion that the IoT industry is on the verge of collapse, with lower productivity and more security hazards The benefits of API in IOT IoT is a popular technology that is here to stay a little longer than one might anticipate IoT devices will be difficult for businesses and end users to utilize if there is poor API administration, therefore its effective utilization depends on the extent of API management As follows: • • • • • • When it comes to IoT devices, effective administration and handling can provide developers the power to choose which API to use and when to withdraw access For apps and IoT devices, developers are free to establish one or more connection requirements An important step in the process that further assists early detection of any unforeseen caveats and failure chances is continuous API monitoring It gives a clear picture of the use and utility of APIs for IoT As one compares the standard experience and provides an end-user experience to identify the gaps, deeper insights into the developer experience with the API may be gained IoT programming that must access an API in an emergency is completely supported because it provides information on API scaling, use quotas, and throttling With proper management standards being upheld and regular version updates, updating API versions is simpler than ever Page 20 P4 Determine a specific problem to solve using IoT 1/ problem We all know, for plants, water is an important factor to ensure the normal growth and development of healthy plants Proper and sufficient watering according to the agronomic requirements of the crop will not cause pests and diseases, limiting pesticides for safe products, achieving high productivity and efficiency However, not everyone has the time to freshen the water at the right time and right for the plant And on a large area, manual watering also takes a lot of time and energy for people Especially for a country that comes up from agriculture like Vietnam, it is very necessary to introduce technology into agriculture On the other hand, at present, our country is in the stage of industrialization and modernization, with automatic machinery and equipment being put into service to replace human labor 2/ Solution Applying IoT technology to solve this problem, an automatic watering system according to soil warmth is researched and developed The system responds to soil and air moisture for plants to grow well, saves water, and facilitates nutrient absorption by plants without leaching, soil degradation, and no environmental pollution With the design of an automatic watering system, people will not have to water the plants, not have to spend money on watering labor as well as monitoring the time to water the plants With this system, the watering will be automatic depending on the weather temperature, sunny or rainy, high, or low humidity, season of the year All those conditions will be entered into the calculation system and given out Exact time to pump water Workers will not need to care about watering plants, plants will grow and develop better thanks to more appropriate and accurate watering Besides, for those who love bonsai but not have time to take care of them, this system will be an effective solution to help people follow irrigation to grow healthy plants With an automatic watering system according to humidity, all activities will be monitored and controlled through the app installed on the phone The device will Page 21 measure the soil moisture, based on the standard humidity installed in the device If the soil moisture is not satisfactory, the LED will light up and the buzzer will sound to notify the user At that time, the pump will automatically water the plants And when the moisture in the soil is satisfactory, the pump will stop working Thus, even if not directly in the garden or farm, we still capture the soil moisture and ensure that the plants are watered continuously and fully, bringing high crop yields
