Mikuska, RobertKabesh, Ahmed2025-09-042025-09-042025-05-12https://hdl.handle.net/2437/397249This thesis presents the design and implementation of a smart home system focused on improving energy efficiency and enhancing security. It leverages the ESP32 microcontroller for wireless communication and low power consumption. The system integrates key components like the DHT22 sensor, PIR motion sensor, RFID module, and relay-controlled devices, all mounted on a custom two-layer PCB. Users can control and monitor the system remotely using the Blynk app. The goal is to offer an affordable, scalable, and user-friendly smart home solution.81enCustom PCB designIOTEmbedded systemsFail-Safe MechanismMicrocontroller based systemEngineering Sciences::EngineeringHozzáférhető a 2022 decemberi felsőoktatási törvénymódosítás értelmében.
