V. Conclusion
In this application, a low-cost, Internet-based data acquisition system has been designed and
implemented that should find interest from researchers. The application possibilities are virtually unlimited by
attaching modules with appropriate interfaces, although the usage of the system is demonstrated with only a few
sample devices. Compared with other applications, this system has advantages in terms of allowing direct
bidirectional communication and reducing overhead, which can be vitally important for some real-time
applications. The operational costs have been reduced by relinquishing the storage of large data to an FTP server
on the Internet. The system is designed to support dynamic IPs. A method to distribute the IP information has
been developed. This cost-minimization effort is a big concern for mobile systems using wireless
communication methods. The overall cost advantage of the system in terms of the components used makes it an
attractive choice for data-acquisition applications. This system can be widely applied to electric power,
