Smart home automation system using Bluetooth technology

TLDR

Conventional home automation systems are typically designed for specific purposes, whereas the proposed system offers a general‑purpose solution that can be easily integrated into existing homes. This study presents a low‑cost, user‑friendly remote‑controlled home automation system built with an Arduino board, Bluetooth module, smartphone, ultrasonic sensor, and moisture sensor, and outlines its hardware and software architecture and future scope. A smartphone application enables users to control up to 18 devices—including appliances and sensors—via Bluetooth connectivity to the Arduino‑based controller. The prototype, equipped with ultrasonic and moisture sensors for water level detection and automatic plant irrigation, was implemented and tested, yielding accurate and expected results.

Abstract

In this paper a low cost and user friendly remote controlled home automation system is presented using Arduino board, Bluetooth module, smartphone, ultrasonic sensor and moisture sensor. A smartphone application is used in the suggested system which allows the users to control up to 18 devices including home appliances and sensors using Bluetooth technology. Nowadays, most of conventional home automation systems are designed for special purposes while proposed system is a general purpose home automation system. Which can easily be implement in existing home. The suggested system has more features than conventional home automation systems such as an ultrasonic sensor is used for water level detection and soil moisture sensor is use for automatic plant irrigation system. This paper also describes the hardware and software architecture of system, future work and scope. The proposed prototype of home automation system is implemented and tested on hardware and it gave the exact and expected results.
