Abstract: The purpose of home automation system using wireless sensor networks are to monitor, control the home appliances based on parameters like illumination, temperature. The home automation system is intended to control all lights and fans in a domestic buildings using data from sensors. The main objective is to reduce the unnecessary energy consumption of a domestic buildings. It is meant to save the electric power and human energy by providing the user with remote control of various lights, fans, and appliances within their home. The system will automatically change on the basis of sensors’ data. This system is designed to be low cost and expandable allowing a variety of devices to be controlled. The proposed system consists of two main components; the first part is the transmitter module which includes sensor nodes to sense temperature and illumination, arduino board for data collection and control and a zig bee transmitter for transferring collected data. Second part is receiver module, which provides appropriate interface to sensors and actuator of home automation system including the appliances to be controlled based on data received. The proposed system is better from the scalability and flexibility point of view than the commercially available home automation systems. A wireless network approach to this communication and control provides an easy, cost-effective and scalable solution to home automation. The home automation systems provide mutual interoperability between various electronic and electrical devices as well as interactive interface for people to control their operation. These features are very helpful to optimize and to economize energy consumption whereby saved energy during some few years could make more money than home automation systems implementation cost. These technologies make peoples’ life also easier, especially for elderly persons and persons with disabilities.
