People who have bad breath sometimes don't know they do. This is The Mint. And it will analyze your breath and let you know just how much it stinks.

The device uses a sensor to measure bad breath causing compounds, including hydrogen sulfide, methyl mercaptan and hydrogen disulfide.

It will also measure water in your mouth's mucus membrane to see if you're dehydrated, because that's one cause of bad breath.

The device is in the midst of a crowdfunding campaign on Indiegogo.
