3. INTRODUCTION
With Home Automation, it has become a very useful concept in the
current era due to its focus on safety, security, energy efficiency,
and user comfort. This advanced system integrates an Android
smartphone, a Wi-Fi module, a Bluetooth module, and a relay
circuit to efficiently manage home appliances. Using wireless
technology, the Android app provides an intuitive interface for
individual device control and monitoring. Commands are sent via
Wi-Fi to the relay circuit, which switches devices ON/OFF based
on user input, offering a highly approachable and reliable smart
home solution.
