“…For this purpose the PV panel is fixed with four photo sensors kept at corners and another one kept at the center [8,9]. The voltages of sensors are read by microprocessor and those from that of orthogonal directions are compared and the orientation of the panel is adjusted by stepper motors as to minimize the error signals.…”

“…During day time both chargers would work in parallel and during night time the wind mill charger might alone work. The earlier sun tracker algorithms (Koyuncu & Balasubramanian, 1991;Balasubramanian & Cellatoglu, 2009) The sun tracker algorithm and the hardware arrangement keep the panel rotated from east direction to west direction all along the day tracking the sun. After sunset, with a delay of a predetermined period of time, the panel is brought to east direction step by step as to keep it set ready for facing the sun next day.…”

The main objective of this presentation is to give the design of main equipments for intelligent home meeting the modern requirements and satisfying most living standards of consumers. In this endeavor the home automation considerations of this presentation focus on manual and remote control of selected appliances, timed setting of switching the appliances and personal digital home assistant software that brings the attention of the resident about the tasks of the day to be performed. Home security concerns of the system are the incorporation of i. real time audio visual system that permits regulated admittance of the visitors after approval from the resident and ii. remote alerting the resident upon detecting the fire or intruder. The design approach is based on the support of the central web server and monitoring unit and is meant for medium sized residential complex constituting many flats. In order to self support the energy needs of the flats to an extent a cost effective dual energy extraction unit generating electricity from the renewable energy resources is also included in the system and fixed in each flat. The performance of all schemes presented here are compared and analysed for their adaptation to any installation. The hardware devices and components used are commonly available in practice and the realization of the system for any further expanded requirements would be quite feasible and easy. IntroductionHome automation activities are becoming increasingly important nowadays in providing more comfort and security for the home residents. Reports are available in the past concerning the development of devices and units needed for implementing the smart home (two websites, 2009; Jorge Caleira Nunes et al, 2004; Renato Nunes, 2003 and Cellatoglu, 2008). Each implementation deals certain aspects of automation satisfying partial requirements of the consumers. This project deals with the design of home automation apparatus satisfying essential requirements of automation needed for comfortable stay and pleasant living in a flat of multi storied building. Also, generating electrical energy from natural resources and their utilization schemes for feeding the apparatus are implemented in the system as to promote contributing to alternate energy 3 www.intechopen.com Smart Home Systems 44resources and to reduce the cost constraints of energy consumption. These schemes are designed to extract maximum solar and wind energy and used to feed selected appliances of the residential flat. In the absence of sun and wind energy the power system lines supplying electricity to the flat would take care of powering the selected appliances. Furthermore, as an additional security concern, an intruder detection system is installed in the system which when detects an intruder would dial automatically a sequence of digits programmed in the system as to give remote intimation for the intrusion found. As internet and telephone communication are quite popularly used nowadays, remote control schemes of selected appliances in...
