With advancement of technology things are becoming simpler and easier for us. Automatic systems are being preferred over manual system. The purpose of this project is to design and construct A GSM based home automation using AVR. Using GSM networks, in this project a home power control system has been proposed that will act as an embedded system which can monitor and control appliances and other devices locally using built-in input and output peripherals. The system has a delay of 2 minutes after the first call to initiate the next command. This project is made up of four vital units. These units are as follows: GSM module unit, peripheral interface control (PIC) unit, driver unit and a power monitoring and control unit. The GSM module is a GSM transceiver which gives the system access to the GSM service provider. The peripheral interface control (PIC) is programmed to carry out the OFF/ RESET operation according to the GSM commands while the driver and control unit consist of capacitors, resistors, diodes, regulators and electromagnetic relay is to effect power switching. The major component that performed the power control of 220v main supply and the automatic voltage regulation (AVR) is the automated electromagnetic relay. The project was realized.

With advancement of technology things are becoming simpler and easier for us. Automation is the use of control systems and information technologies to reduce the need for human work in the production of goods and services. In the scope of industrialization, automation is a step beyond mechanization. Whereas mechanization provided human operators with machinery to assist them with the muscular requirements of work, automation greatly decreases the need for human sensory and mental requirements as well. Automation plays an increasingly important role in the world economy and in daily experience. Automatic systems are being preferred over manual system. Through this project we have tried to show automatic control of a house as a result of which power is saved to some extent. GSM based home automation using AVR is an electronic device that allows a GSM cell phone to monitor and shut down electrical power supply at home where there are emergency or ugly situations such as fire outbreak, lightning strikes, switching surges, transients, neutral failure and other abnormal conditions or malfunctions that can destroy lives and properties. 

 

GSM based home automation using AVR is a system that implements the emerging applications of the GSM technology which enable the users to carry out some task from anywhere in the world via a GSM network, and the system will automatically regulates power surge. The system is made up of a GSM amplifier unit, PIC12f629 microcontroller, power control and a power supply unit. These sub circuits are designed using passive and active electronic components like capacitors, resistors, diode, regulators, transistors, electromagnetic relay, microcontroller and battery.
