Abstract: For monitoring & controlling either home appliances or industry devices networked
embedded systems are important. This proposed work is an attempt to design a data acquisition
system allows information to be collected with no labor requirements, cost efficient and easy to
maintain technology. General web server requires more resources & large amount of memories. So
ARM based servers are becoming popular instead of PC based servers. This paper proposes world’s
most powerful technology using advanced RISC machine (ARM 7) & in-build web server application
with General Packet Radio Service (GPRS) technology. Users can monitor different remote
machines/systems by using embedded web server. GPRS technology along with GSM makes it
accessible from anywhere in the world. Need of server software & its maintenance are eliminated by
this proposed system. This system is an optimized solution for industry automation, instrumentation &
household devices. Various sensors installed at working place help in real time monitoring like
temperature, humidity, carbon monoxide, Speed, LPG gas leakage etc. The results show that design of
system is safe and convenient from local management data. Security of system enhances because of
authentication process. Source code is written in well known embedded C language.

I. Introduction
To study & monitor environmental changes in forests/oceans, surveillance application, home,
laboratories, military & industry automation, it is necessary to monitor & control of physical environments
remotely with great accuracy & ease [1]. So data acquisition & control devices are best solution for unmanned
devices in a multisite job operation. In present days there are very few of companies which are making the Data
Acquisition Devices and the available devices are very costly. Hence, there is need to provide user a cost effective
or low cost device which can suite according to their proposed work. An acquisition unit design to collect data in
their simplest form [2].which is based on Linux [3]; it is popular choice for many embedded PC systems. The
similar system [4] will increases set up costs due to data accessed through central server. For wide range data
transmission typical client-server architecture is not suitable because general purpose computer requires large
space, large amount of memory & more cost. The central server can be removed by using web servers. This
system still based on industrial PC [5]. An embedded web server creates an easy way for monitoring &
controlling any device which is at remote place. Embedded network contains Advanced RISC machine i.e ARM
7 supports real time application also minimizes the system cost. This system detailed in Interactive DAC system
[6]. Remote signals measure & can control through Ethernet module. This system should require PC with internet
at the client side. We proposed a system which is portable, low cost & removes the need of server software &
maintenance by using GPRS technology. It helps to communicate with GSM phone. Now a days GSM has in-
built powerful TCP/IP protocol stack for internet data transfer over GPRS technology. Therefore the status of
different sensors installed at working place can be monitor at anywhere in the world.
The organization of paper is as follows. Concept explains in Section II. Section III will describe the
operation when different sensors connected to the embedded system. In Section IV presents the expected results.
Finally section V concludes paper & suggests some future work.
II. Embedded Web Server Architecture
General PC based web servers, which are developed for general purpose computers like UNIX, LINUX
or NT servers requires large megabyte of memory, a fast processor, pre-emptive multitasking & many more. An
embedded web server provides remote access to devices from a web browser. Static & dynamic information
about industry machineries & system provides same to the web browsers on request by an embedded web server.
An embedded web server is integral part of embedded network [7], which consists of an ARM processor. ARM
processor contains an internet software & application code for monitoring & controlling the systems. Embedded
web servers have lot of advantages; user friendly, low cost, supports to real time application, low maintainability,
portability, high reliability, security, controllability which general purpose computers can not give.
