A vision that is being implemented by many in the world is an extensive range of everyday objects connected and communicating cheaply with each other across a global network - "the Internet of Things." The electronic devices in our world generate enormous amounts of data and thanks to the Internet the possibilities for interaction between devices is almost endless. These devices can be data sources (sensors), end user devices (displays, databases), and even a data source and sink (an actuator, smart phone). The Internet, What is it? How has it developed? Where is it? Who is using it? What can it do? How reliable is it? What’s driving it? These questions will be answered leading to an insight into what is and will likely be possible. Some of the details for implementing Internet TCP/IP end point connections, with comparisons to more traditional methods will be looked at and related to examples for weather monitoring systems and sensors. Using the Internet for weather monitoring raises new issues and there are remaining implementation limitations. Internet communications are scalable and can be used to connect to everything in a weather monitoring network, from a single sensor to a display, to a complete global data network. This not only applies to data connectivity, but also to the network management and maintenance of systems. If it is possible to connect to everything: Do we want to see every measurement? - information overload, smarter presentation tools. Does the quality matter? - quality control algorithms, notifications, data filing. How do we handle the enormous volumes of data? - use and delete or save and backup. Is the information copyright? - legal agreements. And to finish - The skies the limit, or is it?
