Android mobile with Bluetooth using Home Automation Control System
4INTRODUCTION:
Although home automation today is not a new thing but most advanced home automation systems in existence today require a big and expensive change of infrastructure. This means that it often is not feasible to install a home automation system in an existing building.
“Homatic” is a wireless home automation application that is supposed to be implemented in existing home environments, without any changes in the existing infrastructure.
“Homatic” lets the user to control his home from his or her android smart phone. In the smart phone application the user can select actions what should happen with electrical and/or electronic devices in the network.
The past decade has seen significant advancement in the field of consumer electronics.Various “intelligent” appliances such as cellular phone, air conditioners, home security devices, home theaters, etc., are set to realize the concept of a smart home. They have given rise to a Personal Area Network in home environment, where all these appliances can be interconnected and monitored using a single controller.
Home automation involves introducing a degree of computerized or automatic control to certain electrical and electronic systems in a building. These include lighting, temperature control, etc.
This project demonstrates a simple home automation system which contains a remote mobile host controller and several client modules (home appliances). The client modules communicate with the host controller through a wireless device such as a Bluetooth enabled mobile phone, in this case, an android based Smart phone.
