Multipurpose IoT unit for wireless current measurement in HV networks.
Haluška, Daniel ; Kuchař, Karel (referee) ; Rusz, Martin (advisor)
The aim of this thesis is to design and implement a system consisting of a local unit and sensors that enable wireless current measurement in power lines. The introduction focuses on the exploration and detailed analysis of wireless technologies, their properties, parameters, and application possibilities for the proposed system. Furthermore, the thesis examines time synchronization methods to achieve coordinated current measurement across different phases of the power lines. The result of the thesis is a developed device model, its circuit design, software solution, and mechanical construction. A significant part of the work is dedicated to the implementation of the system's software solution and communication based on the ESP-NOW protocol.

Intelligent wattmeter with network communication options (Ethernet / WiFi)
Haluška, Daniel ; Juráň, Radovan (referee) ; Rusz, Martin (advisor)
The goal of the Bachelor Thesis is the implementation of a measuring device for measuring alternating voltage, current and calculating of power consumption. A voltage divider with one-way offset is used for voltage measurement, and the ACS712 integrated circuit with a Hall sensor provides electric current measurement. The Arduino singleboard computer, for which the OLED display is suitable, takes care of the representation and calculation of the electrical power. Furthermore, this device allows communication with the Internet and through the server allows a simple graphical display of measured data. The manufactured measuring device allows measuring power regular outlet up to 3680 W.
