Home Automation using GSM and Arduino :

Main purpose is to provide the user with comfort and access to control his devices from anywhere in the world.

  The user can control his home appliances like air conditioners, fans, lights or music systems etc from anywhere in the world by just sending  a simple pre-defined SMS command to a particular number, user received the acknowledgement for his action. User can check the status whether his device is on or off at that moment. 

Automatic gates for his house or garage, IR motion sensors or smoke or fire alarms can also be added to alert the user in case of any emergency situations by SMS  and by using  GPS  it can send  SOS message to rescue teams with exact location.
