The article presents the IoT architecture in the smart agriculture model and a schematic model of an automated agricultural system that integrates data from various subsystems using artificial intelligence (AI) algorithms, enabling notifications to be sent to farmers' phones and effective management of fertilizers, pesticides and water, which contributes to increased crops. [PERSON] et al. in [35] summarizes the application of IoT technology in agricultural automation, analyzing its implementation in various agricultural systems such as management, monitoring, control systems and unmanned machines. IoT-based communication technologies used in agriculture, such as Wi-Fi, LoRaWAN, mobile communication (2G, 3G, 4G), ZigBee and Bluetooth, were also discussed. The article points to the limitations and prospects for the development of the IoT in agriculture, emphasizing that the future development of communication technologies such as 5G will enable a broader and faster use of the IoT in various agricultural processes, which will contribute to the automation of agriculture, improving the quality and efficiency of crops and reducing the labour input. [PERSON] et al. in [36] highlight the importance of infrastructure, especially bridges, which are key national resources and important for socio-economic development. Draws attention to the need for regular and effective auditing of bridges, which are particularly susceptible to damage and require frequent inspections, to avoid the risk of serious damage that could threaten life and property. The article discusses various techniques used in auditing the health of bridges. [PERSON] et al. in [37] article presents a systematic review of current knowledge about indoor air quality monitoring systems based on IoT technology. It focuses on design aspects such as types of sensors, microcontrollers, architecture, and connectivity, and it discusses problems related to the implementation of research published in 2015-2020. The review shows that 70% of studies focus on monitoring thermal comfort parameters, 65% on CO\({}_{2}\) levels, and 27.5% on PM levels, while 37.5% and 35% of systems are based on Arduino and Raspberry Pi controllers The article also indicates that only 22.5% of studies used calibration before system implementation, while 72.5% of systems claim energy efficiency. [PERSON] et al. in [38] discuss the problem of traffic jams, which are common in almost every urban area worldwide, and the importance of managing traffic using real-time information. It focuses on traffic control systems based on IoT technology, describing their hardware and software systems and analyzing their operation in an urban context. The study highlights both the advantages and disadvantages of IoT-based traffic control systems, emphasizing that while they have their benefits, they also have certain limitations that must be considered in their design and implementation. [PERSON] et al. in [39] provides a comprehensive overview of the application of IoT technologies in smart cities, which enable the integration of various devices and technologies, eliminating the need for human intervention. It describes the basic components of the landscape of IoT-based cities and the technologies enabling the operation of these systems, including architectures, network technologies and artificial intelligence algorithms used in smart city systems. The paper also reviews the most commonly used practices and applications in various smart city domains and discusses the challenges of implementing IoT systems in cities while offering countermeasures. [PERSON] et al. in [40] review existing IoT-based solutions in waste management systems in smart cities, highlighting their role in ensuring sustainable development. It analyzes 16 research articles from the last 5 years to present the state of knowledge about IoT solutions in monitoring waste levels, technologies used and possible solutions.
