The machine I have designed is supposed to detect smells by sucking in some of the smell through a vent in the front. Then, the particles in the air are detected by the small detectors in the air vents. The information collected is then sent to your phone, where it is then sent to a server for processing. Once it is processed, it is sent back to your phone where you can see what smell it is. At the back of the machine, there is a clip for you clip it onto.  There are buttons on the sides to control the machine, and a charging port on the bottom. The top opens up, but the front isn’t supposed to open but theres no other way to show what’s inside the prototype.
