SMS(GSM)BASED HOME AUTOMATION SYSTEM PROJECTS-ECE/EEE/E&I/ICE

  1. 1. Gsm Based Advanced Home/ Industrial Automation Controller System What is GSM ? GSM, which stands for Global System for Mobile Communications, is a digital cellular radio network operating in over 200 countries world-wide. It provides almost complete coverage in western Europe, and growing coverage in the Americas, Asia and elsewhere. MAASTECH 89. RANGARAJAPURAM MAIN ROAD(NEAR SBI BANK) KODAMBAKKAM CHENNAI-600024
  2. 2. Of special interest is the capability of the GSM network to be used for data computing. Most people think of voice calls when they think of cellular phones. But because GSM is digital, you can connect your GSM-enabled phone to your laptop computer and send or receive e-mail, faxes, browse the Internet, securely access your company's LAN/intranet, and use other digital data features including Short Messaging Service.

  3. 3. The unique roaming features of GSM allow cellular subscribers to use their services in any GSM service area in the world in which their provider has a roaming agreement. That means the phone you use in France could work in Germany, Australia, Finland and even China, depending on your provider's roaming agreements. GSM-enabled phones have a "smart card" inside called the Subscriber Identity Module (SIM). The SIM card is personalized to you and you alone. It identifies your account to the network and provides authentication, which allows appropriate billing. Aim of project Imagine being able to control all the electrical appliances of your home from virtually any place your are in the world! For example, say one cold winter day, you are stuck in traffic on the motorway after a long day at work. By pressing a few keystrokes on your mobile phone, you activate a macro which turns on the heating, prepares your Jacuzzi, switches on your electrical fireplace and lava- lamps at your premises. In today's times the GSM mobile terminal has become one of the items that is constantly with us. Just like our wallet/purse, keys or watch, the GSM mobile terminal provides us with a communication channel that enables us to communicate with the world. The want for a person to be reachable or to call anyone at any time is very appealing. MAASTECH 89. RANGARAJAPURAM MAIN ROAD(NEAR SBI BANK) KODAMBAKKAM CHENNAI-600024
  4. 4. Using the cybernetic concept of action space, we in fact extend the action space of the human with the mobile terminal, enabling the subscriber to talk to another subscriber and thus exchange information, issue or receive commands. In this project, we will explore ways of extending this notion of Home Automation by applying mobility to it using various technologies that are available in our information age. These technologies include mobile communication devices and the Internet which are becoming part of our everyday lives. Working of the project: As mentioned earlier our project consist of sensors for detecting abnormal situations and the data is sent to a remote user through a GSM Modem connected to the project. (Intruder sensed, Flame sensed). Also the user can send a SMS Message to activate a device which is connected to the project. For eg a Tubelight or fan any electrical device. The user gets a reply SMS on his phone whether the device is switched on or off. Hardware Spec: MAASTECH 89. RANGARAJAPURAM MAIN ROAD(NEAR SBI BANK) KODAMBAKKAM CHENNAI-600024
