description: The subject of the graduate qualification work is âThe development of a mobile device activity detectorâ.Â The given work is devoted to the development of a mobile device activity detector based on STM32.Â The main goal of the work was to simulate the printed circuit board (PCB) of the final device on EasyEda and the following implementation of the circuit based on the STM32 microcontroller. The main objectives of the final qualification work were formulated as studying of radio frequency signals of mobile communications, highlighting the features of the use of operational amplifiers in the radio frequency range, analysing the methods for detecting radio emission, developing a schematic diagram of a device for detecting mobile device activity, moreover the development of the PCB based on microcontroller STM32. While working on this paper, a schematic diagram was created, converted into a PCB, and the physical implementation of the PCB was made.Â The device I developed detects the presence of a mobile phone, signaling its proximity through the LED. It can be used to prevent unauthorized use of mobile devices in private areas with a high level of information security, to eliminate potential filming that violates legal regulations, and to detect interference with related equipment. My decision to add the STM32 microcontroller to the circuit diagram significantly upgrades the mobile device activity detector, creating an environment for new possibilities.Â Â Â
