A SMART SWITCH TO CONNECT AND DISCONNECT ELECTRICAL DEVICES AT HOME BY
USING INTERNET, IEEE – 2016
AIM:
The main aim the project is to establish a server for Remote Access Terminal using GPRS
Enabled Embedded Server as main communication protocol from powerful
microcontroller.
COMPONENTS:
LPC2148 (ARM7), GPRS Modem, Cell Phone which can support JAVA Application,
Intelligent appliances.
EXISTING METHOD:
The rapidly advancing mobile communication technology and the decrease in costs make it
Possible to incorporate mobile technology into home automation systems. In olden days we
were not monitoring the Office and Home appliances by sitting at one place. We had
controlled those appliances manually; it takes more time to for controlling. This is
disadvantage here like time consuming.
PROPOSED METHOD:
We can overcome the disadvantage of the existing method by Remote control via the
Internet and it’s a new feature and used in home automation systems. However, providing
a mechanism for interaction between devices in this environment is quite challenging. The
internet has been mostly used to connect personal computers so far, but shortly all kinds of
appliances with embedded computers will exchange information over the Internet. A
massive no of microcontrollers are available in today’s devices which can be linked to the
Internet. If these intelligent appliances could be connected to the Internet at low cost, the
way we control and manage their functions would change entirely. The embedded system

requires a network interface such as Ethernet, a TCP/IP protocol stack, embedded web
server software and static and dynamic web pages that form the user interface for that
specific device. The system uses a compact circuitry built around LPC2148 (ARM7)
microcontroller programs are developed in Embedded C. Flash magic is used for loading
programs into Microcontroller.
SOFTWARE
: Embedded ‘C’
TOOLS
: Keil uVision, Flash magic
TARGET DEVICE
: LPC2148 (ARM7)
APPLICATIONS
: Household & Industrial applications, Security applications & Used
For lab monitoring system.
ADVANTAGES: Reduction in Manual power, Cost is reducing & Time saving. Low cost easy
to implement and low power consumption and controlling is done by using web
technology.
CONCLUSION: A system for remote access terminal using GPRS enabled embedded server
is designed in this paper. Using cellular services such as SMS and GPRS to users can control
and manage the intelligent appliances using a GPRS network over the internet.
