Android Based Home Automation Systems and Its Applications

The ideas related to automation of tasks were in existence during the time of Greeks and after that as well, and during the industrial revolution automation systems were developed. Home automation system is nothing but a term used to describe the working of all household appliances. A centrally controlled LCD touchscreen panel is the best example of home automation system as it is used to control the appliances like air conditioners, heaters, security systems, video systems, audio systems, home theatre installations, kitchen appliances and lighting systems.

In the present time, the technologically advanced world is getting more and more advance as new technology is penetrating deeper into our personal lives even in our homes as well. Home automation system is becoming very popular around the world. Home automation is used to control and monitor electronic security systems, lighting, climate, appliances, audio or video equipment, etc. Home automation is the residential extension of a building automation, and it is an automation of the home, housework or household activity. The benefits of automation are that it is secure and saves money, time, maintenance costs, and makes life easier. Home automation devices include X10, Insteon, UPB, Z-wave, Crestron, Lurton-RA, PLC, etc.

Home automation systems are categorized into the following three types depending upon the type of wired or wireless controllers:

  • Power Line Based Home Automation
  • Wired or Bus Cable Home Automation
  • Wireless Home Automation

Generally in today’s modern world human beings are addicted to using modern equipment. The intention of this project is to make an Android OS based smartphone or tablet workable for controlling each and every appliance of industries or household. There are several Android applications available in the market to turn our Android-based smart phone or tablet into a remote control for our home. If we want to control a system in home or want to get start, we need an INSTEON controller and also INSTEON controllable devices. In addition to this, we need to install different Android applications for home automation. Some of these Android applications are INSTEON Hub, MobiLinc, Conductor, wdISY, Touch Switch, Auto HTN Vera, etc.

For a better and simple understanding of this concept, this project for home automation with Android application is handy:

Project Description

Power supply consists of four stages: transformer, rectification, smoothing, and regulation. In the first stage, the transformer steps down the AC voltage within the range of 12v. In the second stage, a bridge rectifier is used to convert an AC current input into a DC current output. In the smoothing stage, AC ripples are removed with the help of a capacitor, and in the regulator stage, a regulator IC is used to regulate the power supply as per the requirement of the circuit.

In recent years, technology is advancing and houses are becoming smarter by gradually shifting from conventional to centralized switches. Conventional switches are located in different places of the house. These switches are difficult to operate for the users and especially for physically handicapped people as they are difficult for them to approach and operate. Android technology based remote controlled system provides a simple solution to home automation.

In this project, a microcontroller is used from the 8051 family, and the loads are interfaced with the 8051 microcontroller by using TRIACs and Opto-Isolators. The remote operation is achieved through any Android smartphone with a Graphical User Interfaced based touch screen operation. GUI is nothing but a type of user interface that allows users to interact with the electronic devices through visual indicators and graphical icons. These can be found in mp3 players, gaming devices, industry equipment and house hold appliances. In order to achieve this, Android smartphone acts as a transmitter and sends on or off commands to the receiver where loads are connected. So, by using wireless technology, we can operate the remote switch on the transmitter and the loads can be turned on or off remotely.
