The MilkMaid is a crowdfunded smart milk jug that users can remotely access via a free iPhone app. The glass jug plugs into a smart base, which remains in your fridge. MilkMaid can detect if your milk is spoiled, or how soon it may spoil, using pH sensors. A weight sensor in the base alerts you to how much milk remains, and a temperature sensor warns when milk is left out of the fridge for too long. Pricing should be announced in June.
