Bezdrátový systém senzorů a aktuátorů pro chytrou domácnost

Abstract

This work deals with the design and implementation of wireless sensors and actuators for the smart home. Its goal is to create a system that can be used in practice with several devices enabling mutual wireless data transmission. 6 different devices for data display, room air quality measurement, wireless button, wirelessly controlled socket, infrared signal receiver and remotely controlled RGB LED strip are created for the base. The theoretical proposal first deals with the very concept of a smart home and its properties. This section includes the programming environment used and the addition of the ESP32 programming platform. The next part is the interpretation of the software solution, which describes the used ESP-NOW communication protocol and communication design, together with the created library and a description of the basic software solutions of individual devices. The next part is devoted to the creation of these devices - from the physical appearance to the internal wiring and creation of components. Completion is devoted to successes and failures in creating this work.
