What is IoT?
IoT, acronym for “Internet of Things”, refers to a technological concept in which physical objects, devices and machines are connected to the Internet and to each other to exchange data and information autonomously. In a nutshell, it's about making objects and devices communicate with each other via the Internet.
IoT involves a wide range of objects and devices, from simple sensors and wearable devices to smart appliances, connected vehicles, industrial monitoring systems and many other applications. The main idea is to make physical objects “intelligent” and able to collect data, communicate with each other and with users, and make decisions based on this data.
Some examples of IoT applications include home automation (remote control and automation of lights, thermostats, security systems and other household devices), healthcare (health monitoring devices, such as smart watches and blood pressure monitors connected to the Internet, which can transmit data to doctors) industry (use of IoT sensors to monitor production, machine maintenance and optimization of industrial processes) agriculture (monitoring of agricultural land through sensors to improve crop management and irrigation) and connected vehicles (cars connected to the Internet that can collect data on vehicle performance and safety and provide advanced navigation services).
IoT has the potential to dramatically improve efficiency, security, and convenience in many areas of daily life and industry. However, it also presents challenges in terms of data security, privacy, and managing the enormous amounts of data generated by connected devices.
What are the benefits of IoT?
- Improved operational efficiency: allows real-time monitoring and data collection from devices, machinery and processes. This data can be analyzed to identify inefficiencies and optimize operations. For example, in manufacturing industries, IoT can be used to monitor production and predict machine maintenance so as to avoid costly downtime. In addition, in agriculture, IoT can help growers optimize the use of water and fertilizers, reducing waste.
- Improving the customer experience: allows companies to collect data on customer behavior and preferences. This data can be used to personalize products and services, offering a more relevant and satisfying experience to customers. For example, IoT devices such as smart speakers can use the user's voice data to provide personalized recommendations or suggestions based on previous interactions.
- Increased security and security: it is possible to improve security in various settings. For example, in home security systems, IoT sensors can detect intrusions or incidents and send notifications to users or competent authorities. In smart cities, IoT can be used to monitor traffic and improve road safety. In addition, in the healthcare and industrial sectors, IoT can be used to ensure a safe work environment by constantly monitoring conditions and detecting potential hazards.
How it works
The Internet of Things (IoT) works through a combination of hardware, software, and network connections that allow physical devices to communicate with each other and with data management systems via the Internet. Here's a simplified overview of how IoT works:
- IoT devices: In the beginning, there are physical devices, such as sensors, actuators, cameras, smartphones, smart appliances, connected vehicles, etc., that are equipped with specific hardware components, such as sensors, microcontrollers and network connectivity (Wi-Fi, Bluetooth, cell phones, LPWAN, etc.).
- Data collection: IoT devices collect data from their sensors or interact with their surroundings. This data may include information such as temperature, humidity, GPS location, fuel level, biometric data, images, videos, and more.
- Data communication: the data collected by IoT devices is sent over the network, usually the Internet, to a server or a data management system. This communication can be carried out in a variety of ways, depending on the connectivity technology used by the devices.
- Data management system: a data management system, often cloud-based, receives data from IoT devices. This data can be processed, stored and analyzed in real time or later, depending on the needs of the application.
- Data processing and analysis: IoT data is processed and analyzed to extract useful information. This analysis can include creating charts, identifying trends, activating notifications in case of critical events, machine learning for predicting or recognizing patterns, and more.
- Data-based actions: based on the information obtained from the data analysis, it is possible to make decisions and implement actions. For example, a smart thermostat could automatically adjust the temperature in a home based on the temperature data collected and the user's preferences. An industrial monitoring system might send a preventive maintenance notification when data suggests that a machine is showing signs of wear and tear.
- Interaction with users: users can interact with IoT devices and access data through mobile applications, desktop software or web interfaces. They can also receive notifications and control devices remotely, when necessary.
In short, IoT allows physical devices to become “smart” and to communicate data in real time or near real time through the Internet, allowing for more effective monitoring, control and optimization of a wide range of applications, from smart home devices to industrial automation and smart city management.
Why choose the Xacria solution
The importance of having a modular solution that allows you to integrate into the field with different types of equipment and sensors, even from different manufacturers, and at the same time to provide the collected data to multiple data analysis platforms was the key idea for the construction of the solution proposed by Xacria.
The Xacria IoT solution consists of three subsystems that can be composed according to customer integration needs: Field, Collection and Analysis.
The subsystem of Field consists of microcontroller devices, created in partnership with CREOTEC, for the management of field sensors; for example, weather sensors, vibration sensors/accelerometers, shooting sensors and a whole series of other sensors that allow the detection of measurements. These field devices are not limited to mere data collection but allow a complete management of the sensors (onboard, configuration, reading); in addition, if necessary, they allow on edge processing according to logics that can be managed by injectable code. The data collected and processed are sent according to various types of communication (LoRa, NB-IoT, 3G/4G etc.), depending on the modules configured on the card, to the data collection gateways. The devices offered have been designed in such a way that they are modular and can accommodate the different requests from the customer. The serialization of the transmitted data follows the standard Protobuf in order to allow open integration with third-party management systems.
The subsystem Collection deals with the collection of streaming data from field devices. Thanks to the microservice architecture, which operate in streaming, it allows simple integration with any type of field device; an SDK allows the development of integration microservices. The raw data collected is processed in streaming in order to be transformed, enriched, aggregated, saved on a database, in addition to the calculation of KPIs when necessary. A special WEB interface allows the management of field devices, for the entire life cycle (onboard, configuration, firmware update, decommissioning), in addition to the display of diagnostic data (alarms, consumption metrics, etc.) and field metrics (data from sensors). Finally, appropriate integration microservices in northbound allow the use of data collected from external data centers, according to the formats requested by customers.
The subsystem of Analysis, created using a database NoSQL, allows the visualizing of the data collected by the sensors in time tables or the creation of custom graphs of different types in order to provide the customer with a customizable interface that allows specific analyses.
The three subsystems that make up the Xacria IoT solution are totally independent of each other and allow integration with existing external systems in order to meet all those customers who already have established solutions and need only certain parts of the data collection or processing process.
Use cases of the Xacria solution
The Xacria IoT solution has been adopted in various areas by small and large companies. For example, part of the solution was adopted by an Italian energy company for environmental monitoring using weather, vibration and shooting sensors. Thanks to the modularity of the solution, it was possible to achieve an integration perfectly in line with the customer's needs.
Other use cases, created in collaboration with CREOTEC, concern home automation and application to the world of agriculture.
