AGRISERVER is a sensor network with software for agricultural use. It has been operating for more than 6 years in a vineyard, a chestnut orchard, an apple orchard, and a green-house in Obuse, Nagano Prefecture, Japan. It provides data on temperature, humidity, and solar intensity at each farm, as well as crop images, through the Internet. It has supplied large amounts of data for us in multiple applications in agriculture-related industries. To distribute the AGRISERVER data to the public, we opened a new portal site, "Know-Live". We propose several applications for the effective use of the data, including cultivation and management, food-chain traceability, agribusiness advertising, education, communication between farmers and consumers, and agritourism. Discussions on the applications confirmed that AGRISERVER can be a powerful tool, especially in an agriculture- based society such as that in Obuse.<br>
