Did you ever experience that sinking feeling when you pour your milk into a freshly made mug of tea and the milk breaks into a million bits? Gone-off milk is all too familiar to us, especially in the summer months when leaving milk out for any length can end in pouring it down the sink.
Introducing the ‘smart milk jug’ or the ‘Milkmaid’, a jug that sits neatly in your fridge and through LED lights, tells you when your milk has gone bad. Not only that, it also measures how much milk you have left and sends a text message to your phone to get more milk. Here’s how it works. The milk goes into the jug, and as it begins to go off in the fridge, a set of pH and temperature sensors located in the jug’s metal base will relay that information to the pedestal or ‘SmartBase’ which the jug sits in. Also nestled inside the SmartBase is a weight sensor to detect how much milk is left in the jug, along with a GSM radio module, an antenna, a SIM card, and a hefty rechargeable battery to keep the whole thing humming along. And to top it off, the Milkmaid is a very attractive addition to your fridge.
The smart device was the winner of a Quirky and GE competition run in early May where people were challenged to come up with ways to improve everyday objects by making them smarter with software. Quirky and GE then took the winning idea and got to work on designing and engineering a user-friendly and eye-catching product by 31 May 2012.
The Milkmaid is the result, and it remains to be seen if there will be a demand for it, or whether we prefer to rely on our own sense of smell, and weighing the carton.
