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 videocamera that broadcast a still image to their desktops about three times per minute — enough to determine the level of coffee in the glass Several years later, that coffeepot had become one of. | the hammersmith group research report february 2010 The Internet of things Networked objects and smart devices the hammersmith group new york 203 rivington street suite 3a new york ny 10002 massachusetts 259 south main street bradford ma 01835 t 917 447 8800 f 978 372 2949 the hammersmith group It all began with a coffeepot.

That coffeepot was a proof of concept for today s networked objects and the Internet of 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. The question is no longer is this possible but rather will this feature bring me enough new customers to offset the small marginal cost of the hardware said Mike Kuniavsky a partner of ThingM a ubiquitous computing device studio. The Internet of Things3 comprises a digital overlay of information over the physical world. Objects and locations become part of the Internet of Things in two ways. Information may become associated with a specific location using GPS coordinates or a street address. Alternatively embedding sensors and transmitters into objects enables them to be addressed by Internet protocols and to sense and react to their environments as well as communicate with .
