Abstract: The paper is to develop a system, which uses mobile technology that keep control of the various units of the automobiles, which executes with respect to the signal sent by mobile. Now a day's every system is automated in order to face new challenges in the present day situation. Automated system has less manual operation, so that the flexibility, reliabilities are high and accurateAs a result, automated control solutions are preferred in every industry. Automated systems, particularly in the field of electronics, are performing better. The fact that the worldwide system for mobile communication is an international standard is probably the most useful thing to know about it. GSM is the only type of cellular service available in some parts of the world. GSM was created as a replacement for analogue service. For the use of appliances, a new concept has been developed to manage them remotely using GSM, allowing the user to control the switching of domestic appliances from a distance. The devices may be turned on/off and the status of the devices can be relayed to the specified cellphone number programmed in the microcontroller by sending a simple SMS to the GSM modem at a remote location.
