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 al...
