Due to the importance of the environment on animal production and thus environmental control, the study aims to build a system for monitoring and control the meteorological variables, temperature and relative humidity, low cost, which can be associated with an evaporative cooling system (ECS). The system development included all the stages of assembly, test and laboratory calibration, and later the validation of the equipment carried in the field. The validation step showed results which allowed concluding that the system can be safely used in the monitoring of these variables. The controller was efficient in management of the microclimate in the waiting corral and allowed the maintenance of the air temperature within the comfort range for dairy cattle in pre-milking with averaged 25.09 ºC during the afternoon. The equipment showed the lower cost (R$ 325.76) when compared to other middle market (R$ 450.00).

Aiming at the presently slow informationization development phenomenon in the drawing and coving workshop of textile enterprise, we analyze actual existing problems in production management and information development, use some theories and techniques to propose many solutions. According to the actual requirements of workshop, we implement a real-time monitoring and control system based on LAN. System’s structure and workflow, the key techniques within the system development are researched, the accuracy of production data is ensured by using numerical approximation theories. As proved by practice, the system's structure is simple, easy maintenance and low cost, meantime, furthermore, system can run stably, collect accurately production data, and its functions meet production control and information management of workshop needs.

Place of monitoring and control of risks of financial stability of the state in the system of ensuring financial security of the state was substantiated. Methods of identifying threats to Ukraine's financial security through the current and strategic analysis of financial system development indicators were considered. Tendencies of economic development of Ukraine in the context of revealing sources of threats to financial stability of the state were analyzed. Dynamic analysis of the actual values of the financial security indicators of Ukraine as a whole and its separate components had been carried out. Threats to Ukraine's financial security were identified based on comparative and trend analysis. Reasons for the critical state of debt, banking and monetary security in the financial structure and the preconditions for the emergence of systemic threats had been investigated. Systematization of risks and threats to Ukraine's financial security by its components had been carried out. Influence of systemic threats in the financial sphere on the economic security of the state was generalized. International experience of monitoring financial stability of the state was analyzed. Additional risks to the national financial system are associated with the globalization and digitization of the state financial system that are not taken into account by valid methodological recommendations for calculating the level of economic security of Ukraine were highlighted.

As the development of IoT technologies has progressed rapidly recently, most IoT data are focused on monitoring and control to process IoT data, but the cost of collecting and linking various IoT data increases, requiring the ability to proactively integrate and analyze collected IoT data so that cloud servers (data centers) can process smartly. In this paper, we propose a blockchain-based IoT big data integrity verification technique to ensure the safety of the Third Party Auditor (TPA), which has a role in auditing the integrity of AIoT data. The proposed technique aims to minimize IoT information loss by multiple blockchain groupings of information and signature keys from IoT devices. The proposed technique allows IoT information to be effectively guaranteed the integrity of AIoT data by linking hash values designated as arbitrary, constant-size blocks with previous blocks in hierarchical chains. The proposed technique performs synchronization using location information between the central server and IoT devices to manage the cost of the integrity of IoT information at low cost. In order to easily control a large number of locations of IoT devices, we perform cross-distributed and blockchain linkage processing under constant rules to improve the load and throughput generated by IoT devices.

Irrigation systems are becoming increasingly important, owing to the increase in human population, global warming, and food demand. This study aims to design a low-cost autonomous sensor interface to automate the monitoring and control of irrigation systems in remote locations, and to optimize water use for irrigation farming. An internet of things-based irrigation monitoring and control system, employing sensors and actuators, is designed to facilitate the autonomous supply of adequate water from a reservoir to domestic crops in a smart irrigation systems. System development lifecycle and waterfall model design methodologies have been employed in the development paradigm. The Proteus 8.5 design suite, Arduino integrated design environment, and embedded C programming language are commonly used to develop and implement a real working prototype. A pumping mechanism has been used to supply the water required by the soil. The prototype provides power supply, sensing, monitoring and control, and internet connectivity capabilities. Experimental and simulation results demonstrate the flexibility and practical applicability of the proposed system, and are of paramount importance, not only to farmers, but also for the expansion of economic activity. Furthermore, this system reduces the high level of supervision required to supply irrigation water, enabling remote monitoring and control.

This paper presents the development of a cost-effective automatic system for greenhouse environment control. The architectural and functional features were analyzed in the context of the realization of a controlled-environment agricultural system through all its stages: installation, deployment of the software, integration, maintenance, crop control strategy setup and daily operation of the grower. The proposed embedded platform provides remote monitoring and control of the greenhouse environment and is implemented as a distributed sensing and control network integrating wired and wireless nodes. All nodes were built with low-cost, low-power microcontrollers. The key issues that were addressed include the energy-efficient control, the robustness of the distributed control network to faults and a low-cost hardware implementation. The translation of the supervisory growth-planning information to the operational (control network) level is achieved through a specific architecture residing on a crop planning module (CPM) and an interfacing block (IB). A suite of software applications with flows and interfaces developed from a grower-centric perspective was designed and implemented on a multi-tier architecture. The operation of the platform was validated through implementation of sensing and control nodes, application of software for configuration and visualization, and deployment in typical greenhouses.

The concepts of effluent irrigation and aerobic composting of organic solid wastes are not new, but the meat industry in New Zealand has developed these concepts further in recent years for effective treatment and recovery of resource in meat processing wastes. Significant advances have been made in developing design, operation, monitoring and control of these low-cost simple technologies, which are well suited for the treatment and utilization of meat industry wastes in New Zealand. The feasibility of utilizing these high-strength organic wastes for organic farming has been demonstrated.
