In this age of digitization and automation, the usage of the internet has invaded every part of our lives. It provides a space for wirelessly connected, programmable devices via a network infrastructure, or "internet of things" (IoT). An IoT-based smart home is proposed in this study. The smart house can be controlled manually or automatically thanks to the technology. The relay mode and the mode selector, which can be used to choose the mode, are the two main components of the proposed system. Hardware implementation can be used to test the proposed system effectively. It may be automatically controlled with a virtual switch through an Android app. When the manual mode is selected, the automated mode is turned off, and vice versa.
