A Beer by the Sensor The much-hyped Internet of Things may someday arrive as promised. While we wait, maybe we should grab a pint of good beer? That is where new technology from an Indiana start-up firm could come in handy. The company, SteadyServ Technologies, showcased technology this week to help bars and restaurants - and maybe even patrons - keep track of the beer remaining in a keg. The company puts a donut-shaped sensor under every keg - essentially a scale - that sends a wireless signal to an app about how fast the beer is being consumed and how much is left. The system is meant to take the guesswork out of beer orders so your local pub should be able to more efficiently stock the draft that customers love. And for those who like to belly up to the bar, that means they should never again be told that their favorite tap has run dry. Most of this technology should remain out of view of beer drinkers. But the company hopes that as craft beers grow more popular, the technology could also be used to lure drinkers to a place with a ready supply of a hard-to-find brew. With SteadyServ's constant stream of data, a bartender could write a tweet when tapping a keg of beer, then another when the keg gets low. "They can say, "Better hurry up - only 32 pints of Brooklyn Pale Ale are left,"" said Steve Hershberger, SteadyServ's chief executive. It creates a sense of urgency. If this idea sounds familiar, it's because thirsty computer programmers have been using the Internet for decades to issue early warnings when a preferred drink was running low. As far back as 1982, people in Carnegie Mellon's computer science department wired a Coca-Cola vending machine to update them at their terminals to the quantity and temperature of bottles. A primary motivation for the networked Coke machine, according to a history on the university's website, was that, "It got rather annoying to traipse down to the third floor only to find the machine empty." There weren't any sensors or wireless signals or smartphones used for that system. But people were thirsty then, and they're thirsty now. And you can't blame a company like SteadyServ for trying to improve the Internet of Things to drink and eat, and to slake everyone's thirst in a more satisfactory fashion.
