The aim of the thesis is the practical implementation of an ultrasonic radar system based on IoT technology solutions, along with the preparation of software and its implementation. The project was carried out using an ultrasonic sensor HC-SR04, SG90 servo, 1.8" TFT LCD display and Arduino Nano v3.0. The stages of work included: selection of appropriate components, designing a prototype of the radar with a 3D model of the casing, building up and programming the device. Distance sensors, which are most often used in different fields, were also discussed. The elements used in the ultrasonic radar are presented, as well as programming and design environments used throughout the process. The last stage summarizing the work is intended for testing the device and conclusions.
