It all began with a coffeepot. A coffeepot that was connected to the Internet (before it was even called the Internet) and which provided information about its status (long before there was Twitter). In 1991, researchers at Cambridge University shared a single coffeepot among several floors. The researchers were frustrated by the fact that they would often climb several flights of stairs, only to find the coffeepot empty. They set up a video camera that broadcast a still image to their desktops about three times per minute — enough to determine the level of coffee in the glass pot.1 Several years later, that coffeepot had become one of the first Internet web cam sensations, with millions of hits worldwide. That coffeepot was a proof of concept for today’s networked objects and the Internet of Things.2 Since then, the price of processing power has dropped significantly, and a number of projects are demonstrating the benefits of adding processors, sensors, and transmitters to a range of objects.
