Pachube is a web service available at pachube.com that enables you to store, share & discover realtime sensor, energy and environment data from objects, devices & buildings around the world. Pachube is a convenient, secure & scalable platform that helps you connect to & build the 'internet of things'.
As a generalized realtime data brokerage platform, the key aim is to facilitate interaction between remote environments, both physical and virtual. Apart from enabling direct connections between any two responsive environments, it can also be used to facilitate many-to-many connections: just like a physical "patch bay" (or telephone switchboard) Pachube enables any participating project to "plug-in" to any other participating project in real time so that, for example, buildings, interactive installations or blogs can "talk" and "respond" to each other.

Pachube is a little like YouTube, except that, rather than sharing videos, Pachube enables people to monitor and share real time environmental data from sensors that are connected to the internet. Pachube acts between environments, able both to capture input data (from remote sensors) and serve output data (to remote actuators). Connections can be made between any two responsive environments, facilitating even spontaneous or previously unplanned connections. Apart from being used in physical environments, it also enables people to embed this data in web-pages, in effect to "blog" sensor data.

Pachube makes it simple to build applications, products and services that bridge physical and virtual worlds. With a rapid development cycle (it can take just one line of code to start prototyping), and a sophisticated development path (working with both web-protocols and data formats that are interoperable with construction industry formats) people have used Pachube to build sensor-logging systems, remote monitoring apps, integrate building management systems, develop geo-tracking systems, create mashups and networked objects and a whole host of other things.
