Sensordrone project aims to add all sensors missing in your smartphone, like a breathalyzer

Sensordrone is yet another cool Kickstarter project, which promises a device that can hang on your keyring, and is loaded with most sensors under the sun. It will be made useful by smartphone apps, of course, as the video below demonstrates. It is very similar to the Node project there, and even has the same price tag on Kickstarter.
The sensors inside aim to be accompanied by apps that receive and analyze the measurements, and a few of those are demonstrated, like an air quality apps, for example.
The Sensordrone gizmo is slated for a $199 price when it launches, and if you pledge for it at Kickstarter, you will get it at the introductory $175 tag. Oh, the power of crowdsourced inventions!
