Home Automation System Based on Bluetooth, Gsm and Ethernet

Abstract

With the rising power of technology, we are able to accomplish tasks with increased comfort and at a much quicker rate. Technology has provided us with the ability to communicate, organize, and manage our time in a more efficient manner. Automation of the surrounding environment of a modern human being allows increasing the work efficiency and comfort. The ―Home Automation‖ concept has existed for many years. The terms ―Smart Home‖ and ―Intelligent Home‖ have been used to introduce the concept of networking appliances and devices in the house. The aim of this project is to enable communication between the user and different electrical devices within the home wirelessly. This project is a combined utilization of an Arduino Uno board with the microcontroller(Atmega 328P-PU), a Bluetooth module, a GSM module(SIM 900A), an Ethernet Shield and an android device to create a wireless network that connects the home appliances as a single unit for controlling household appliances remotely using a smartphone. This project is particularly useful for physically disabled/old age people who have difficulty moving and would appreciate the ability to switch ON/OFF their home appliances with minimal movement. It can also be useful in situations where forgetting to turn OFF any home appliance on leaving the home may be corrected and will also enable the user to check the status of the appliances and control them. It may be useful in winters/summers to pre warm/cool the home, if required. The android app for the HAS has been developed using the online software MIT app inventor 2. With the help of the android app we can control and monitor any appliance through arduino, and thus establish a successful communication link between the mobile phone and the microcontroller. Home Automation is undeniably a resource which can make our lives easier with increased comfort and efficiency. The nature of this project is such that it provides a great scope for further developments.
