An Internet Based Interactive Embedded Data Acquisition System for Real Time Application

We present the principles of a low operational- cost but flexible Internet-based data-acquisition system. The main core of the system is an embedded hardware running a light weight C code. The embedded device communicates through General Packet Radio Service (GPRS), send data to main FTP server, which makes it accessible from anywhere in the world. In addition, GPRS provides a bidirectional real-time data transfer allowing interaction. A novel approach is introduced to minimize the operational costs while operating with a large amount of data.
