Design of Data Acquisition and Control System (DACS) is the challenging part of any measurement and control applications. These applications widely use the single chip data acquisition method. But the single chip method has the problem of poor real time and reliability. And it doesn’t able to process with embedded web documents and networked embedded devices. The main objective of this work is to overcome these drawbacks and to design a system for remote I/O data acquisition and control by Linux portable Advanced RISC Machine (ARM) processor and in-build web server application with General Packet Radio Service (GPRS) technology. This system upgrades the general single chip method. Because Linux operating system is the better option for embedded Real Time applications it doesn’t have many real time constraints especially for embedded web server application. The World Wide Web is a global system of interconnected computer networks that use the standard Internet Protocol Suite (TCP/IP) to serve billions of users worldwide. This GPRS module eliminates the need of internet software suite in ARM processor and mass storage for web applications and allows the user to interface with many real time embedded applications like remote DACS and embedded processors like ARM Core.
