For the new unit, Mr. Layman presented us with a very different challenge: Build a prototype of something that detects smell. We later analyzed a series a handheld products such as the temperature gun, a old phone etc… Some classes after that, we created a design sketch to start create a final model. My product is based on a phone and a game controller. My has a filter that takes in the smell and then a in-built smell catalog (in the phone) will scrutinize the smell and then will show results.
