V diplomskem delu je predstavljen sistem za zaznavanje zasedenosti toalete, razvit za potrebe podjetji, kjer se zaradi velike zasedenosti in prostorske stiske toalet odločijo za sistem zaznavanja zasedenosti kabin v toaletnih prostorih. V nalogi je opisano delovanje celotnega sistema zasnovanega na ESP32 mikrokrmilnikih povezanih v Wi-Fi omrežje, ki ga ustvarjajo sami. Predstavljen je okvirni plan razvoja projekta, od preliminarnih raziskav do načrta izgradnje. Opisana je uporabljena strojna in programska oprema. Sledi opis delovanja senzorjev (TF-Luna, ld2410, AJ-SR04M), opis uporabljenih tehnologij za izvedbo detekcije (LiDAR, RADAR, ultrazvok) in medsebojna primerjava kakovosti zaznave. Predstavljeno je delovanje programske kode s podrobno razlago delovanja. V nadaljevanju je opisan postopek konstruiranja ohišja semafora ter razvoj in izdelava tiskanih vezji. Sledi opis vgradnje vezji v ohišje semaforja, končna namestitev izdelanih elementov v pisarne ter celostno testiranje delovanja sistema. V zaključku je povzeta uporabniška izkušnja pri uporabi sistema in potencialne možnosti njegove nadgradnje. The diploma thesis presents a restroom occupancy detection system designed for businesses that face high restroom occupancy and restricted space, prompting them to establish an internal system for monitoring restroom occupancy. The thesis describes how the complete system works, which is built on ESP32 microcontrollers linked to a self-created Wi-Fi network. It details the hardware and software employed and provides an overview of the project's development structure, from basic research to construction planning. The operation of sensors (TF-Luna, ld2410, AJ-SR04M) is described in depth, as are the detecting methods (LiDAR, RADAR, ultrasonic). A mutual detection quality comparison is shown. The thesis goes into great detail about how the software code works. It describes the building of the semaphore housing as well as the design and manufacture of printed circuit boards. This is followed by a demonstration of ...
