Abstract : The rapid development of wireless communication and embedded systems has led to increased adoption of home automation technologies. This project presents a Smart Energy-Saving Home Automation System via Bluetooth that allows users to control household electrical devices remotely using a smartphone. The system is designed to improve convenience, accessibility, and energy efficiency in residential environments. The proposed system uses a microcontroller (such as Arduino or NodeMCU) interfaced with a Bluetooth module (HC-05/HC-06) to establish wireless communication with an Android application. User commands sent from the mobile application are received by the Bluetooth module and processed by the microcontroller. Based on these commands, a relay module is activated to switch electrical appliances ON or OFF. The system operates within a short communication range and provides quick response with minimal delay. The Bluetoothbased approach makes the system cost-effective, easy to install, and reliable for small-scale home automation. It is especially useful for elderly and physically challenged individuals by reducing manual effort. The proposed solution demonstrates an efficient method for implementing basic smart home functionality without complex infrastructure.

Keywords : Smart Energy-Saving Home Automation System via Bluetooth, Home Automation, Wireless Communication, Microcontroller, Arduino, NodeMCU, Relay Module, Android Application, Smart Home System.
