Abstract – In the world of automation we want our daily
SMS sent decides the type of operation. The project is based
life to be controlled remotely. The aim of the project is
on a very simple principle. First, the SMS sent is stored and
controlling of home appliances remotely when the user is
collected from the receiving mobile station and then the

wireless technology (GSM). The system uses GSM technology
intermediate hardware that we have designed according to
thus providing universally access to the system for
the command received from the sent message.
