GSM BASED HOME AUTOMATION
Intoduction:
Home automation (also called domotics) is a field within building automation,specialixing in the specigic automation requirements of private homes and in the application of automation technique for the comfort and security of its residents.
Athough many techniques used in building automation(such as light and climate control ,control of doors and window shutters ,security and surveillance systems,etc.)are also used in home automation, additional functions in home automation can include the control of multimedia home entertainment systems,automatic plant watering and pet feeding,automatic sences for dinners and parties,and more user friendly control interface.When home automation is installed during construction of new home,usually control wires are added before the dry wall is installed.these control wires run to a micro controller,which will then control the encironment.
Implementation methodology:
Wireless communication of various machines and devices in mobile networks is a fast growing business and application area in industry, maintenance business,customer service,security and banking areas.This paper presents design and implementation of remote conrol system by means of GSM cellular communication network. The design integrates the to be controlled, the micro controller .and GSM module so that it can be used for a wide range of applications.
An AVR microcontroller is used to control the home appliances and it will communicate to the GSM modem through the serial port of controller. Most of the home appliances are connected to AC mains so, a special care is to be taken to switch the appliances
