Here is a smart sensor that lets you monitor your wine cellar and avoid wasting wine. The WineMinder measures the temperature and monitors your wine collection to let you know when each bottle is at its best. It gathers data to forecast the shelf life of your collection on a bottle-by-bottle basis.
WineMinder lets you enter your collection into the companion app by taking a photo of labels or entering wine details manually. The user replaceable battery lasts up to 18 months. More information is available on Kickstarter.
