SINGLE PHASE AUTOMATIC CHANGE OVER
ABSTRACT
Gsm controlling electrical system is a low cost solution to Remote Control and Monitoring via your mobile phone. It has 2 relay outputs and 4 contact closure inputs. Outputs can be used to control lighting, central heating boiler, pumps etc and the inputs can be connected to thermostats, security sensors and flood detectors. An optional wireless interface allows communicate with an expanding range of security and fire sensors, heating thermostats for temperature control and panic switches. The advantages of cellular communications like GSM technology is a potential solution for such remote controlling activities. GSM-SMS technology can be used to control household appliances from remote places. The system allows the homeowner to monitor and control his house appliances via his mobile phone set by sending commands in the form of SMS messages and receiving the appliances status as well. This system provides ideal solution to the problems caused in situations when a wired connection between a remote appliance/device and the control unit might not be feasible. The system is wireless and uses the user’s mobile handset for control and therefore the system is more adaptable and cost-effective. The system uses GSM technology.

CHAPTER ONE
1.0 INTRODUCTION
1.1 BACKGROUND OF STUDY
The rapid growth of wireless communication motivated us to use mobile phones to remotely control a household appliance. In this paper we describe a remote appliance control system which can control different household appliances by sending an SMS message from a mobile phone. This controller is extremely handy at places where we have to control the ON and OFF switching of the devices but no wired connection to that place is available. The microcontroller would then control and device based on the information given to it. The proposed solution will need to be easy to use, simple, secure, and robust and be useful on most mobile phones. A remote household appliance control has been described in using internet. A Bluetooth based home automation control is described. A GSM based system for home automation is described which uses voice commands for control. In voice commands for home automation is being described. In this paper we describe a simple remote home appliance control using GSM SMS (Short Messaging Service).
1.2 AIM AND OBJECTIVE;
The seminar intends to interface the microcontroller with the GSM modem and control home appliances by sending the predefined message from the mobile to the controlling unit. The design uses GSM technology and Embedded system to design this application. The main objective of this seminar is to design a system that continuously checks the messages if any, received from the user mobile and changes the status of the system as per the message received from the mobile through the modem.
This seminar is a device that collects data from mobile, codes the data into a format that can be understood by the controlling section. This system controls the relay as per the message received from the mobile.
The objectives of this seminar is to develop a microcontroller based control system. It consist of a GSM modem, microcontroller, the interfacing unit to allow the communication between the microcontroller and mobile and the required circuitry.
