Increasing demands for energy efficiency, transparency in energy resource accounting, and integration into digital monitoring systems highlight the relevance of this topic.

Based on the analysis of the structure and functional elements of an automated natural gas measurement complex, it is proposed to develop a system using an ultrasonic flow transducer, as sensors of this type offer the best combination of accuracy, reliability, and application flexibility.

Various flow measurement methods that are widely used in natural gas flow and volume control systems have been reviewed. The design features and technical characteristics of sensors used for monitoring gas flow, pressure, and temperature have been analyzed. A 3D model of a single-path ultrasonic flowmeter has been developed, along with a model of the electronic computing components layout in SolidWorks. Additionally, a simulation of the system’s operation was carried out in Wokwi.

The aim of this diploma project is to develop an automated system capable of providing continuous monitoring of air quality in an office environment. The system is also designed to detect deviations from acceptable values and to have the technical capability to influence air quality in order to improve and maintain it at a stable level.

The diploma project consists of an introduction, four main chapters, conclusions, and a list of references. It includes 68 pages of main text, 29 illustrations, and 21 references to the literature used.
The aim of this work is the design and development of an automated lighting control system capable of ensuring optimal energy efficiency, adaptive operation, and safe control of lighting devices or the overall lighting system.

To complete the diploma project, the following tasks were formulated:

This work substantiates the relevance of developing an air humidification system for office spaces in accordance with modern requirements for the indoor microclimate of work environments. The focus is placed on the influence of humidity levels on employee health and productivity, disease prevention, and the preservation of technical equipment and furniture.

The thesis includes an analytical review of existing air humidification methods. Based on the analysis, the ultrasonic method was selected as the most effective, economical, and convenient option from the perspective of automation system design. The required humidification efficiency was calculated to maintain a comfortable humidity level in a 60 m² office, which made it possible to determine the system’s technical parameters.
During the design phase, a modular system architecture was developed, consisting of a central hub and subordinate modules. The ESP32S microcontroller was chosen as the main control unit, enabling wireless communication, sensor data processing, actuator control, and interaction with a web interface. Schematic diagrams for the hub and modules were created, with power supplied via USB-C and voltage converters, enhancing the system’s versatility and reliability.
