Remote interrogation and control of sensors via the internet

The Internet seems to be penetrating more and more aspects of the people. Enormous amounts of information are available with just a few keystrokes. In addition, it is possible to put near-real-time sensor information on the Internet. It is also possible to have a level of user control over, or at least interaction with, the Web site providing sensor data, and hence an instrumented platform as well. Limitations do exist for such an installation. The user should have a full-bandwidth connection to the Internet. The Web site should include a robust server. And network delays caused by heavy information traffic should be expected. But even with the delays, evidence from Internet users shows that the response speed is acceptable.
