Smart plug with consumption measurement
Hudák, Filip ; Mišurec, Jiří (referee) ; Lattenberg, Ivo (advisor)
The master thesis is devoted to the design with the following implementation and realisation of the smart socket. The theoretical part discusses already existing solutions on~the market and familiarizes with the methods of measuring the power of electricity, which are used later in the thesis. The next part of the design of the smart socket, the thesis deals with it's own design of the smart socket and the analysis of individual components, from the microprocessor, analog-to-digital converter to the individual components that measure voltage and current. The last part of the thesis involves in the realization of~a~schematic design, the production of printed circuit boards where the circuit boards are divided into two parts, the part with alternating current and the part with direct current. Last but not least, there is a program part that includes the main program for the ESP32 microcontroller and an Android application which displays measured and calculated values, with the possibility of controlling the smart socket wirelessly. The final solution to the given problem is a device that measures voltage and current and displays the results to the user via a web application and an Android application. It will mainly be used in places where it is not possible to offer socket management via the cloud.
