Okay, so from the sound of it, the Kiss Me Meter seems like something that might say, measure your crushes' cooties, attractiveness or aura. But not so, the little Kiss Me Meter is a personal bad breath detector with a LED display so you can eliminate embarrassing situations.

It uses a MEMS gas sensor and is equipped with a re-calibration function so that it can accurately measure the nastiness of your breath. It detects the specific gases from your teeth or stomach, and shows five levels of mouth smell in different colors of LED display.
