This is Scentee - an aroma generating add on that gives your smartphone scent notifications. It'll now be available worldwide.

The $35 smell dongle holds a little scent cartridge with enough fragrant liquid for 100 sprays. It has rose, lavender, coffee, rosemary and strawberry. It can be controlled with an app and it gives off a scented puff on timed intervals. It'll also be an alternative to audio notifications.

And you can also wake up to scents instead of sounds. Set your alarm to sound off with coffee! [Scentee via Electronista]
