As now a day’s technology is increasing very fast. At this time every person wants the technology around him/her. For that the technology should be all over this can be possible only if it is present in our homes, offices etc. In India, we all know that we have to control our home appliances manually. But now a days some appliances are coming in market which can be controlled by phone, remote etc. Suppose if we can control our home appliances with help of sound. Isn't it feel some surprising? But yes we can control our applications with help of sound also, at a cheaper cost. After all these we can say that we are living in between the technology. The proper use of technology is when we all are in between with technologies at any place even at our homes, offices, etc. In this proposed module “smart home” all the appliances will be connect to technology, so that we can use the technology at our home also. In this project we will control our appliances with sound like by flipping our fingers, by making clap, by knocking table and etc. We can control any appliances of our home where we live, offices where we do work and much more. If all our surrounding’s things becomes automated with the use of technology, we can say that our country India is also having technology and are widely using by common peoples. As this model is easy to build at cheaper cost and with required few skills, so everyone can implement it in their homes, offices, industries, colleges, schools, etc. This model will also help in the developing Smart India also.
