Prototype 3

In order to contain my Arduino, breadboard and sensors I decided to laser cut a box. This allowed me to have everything in one place so that I could display it neatly at the round-robin critics event.

For the prototype 3 I decided to include two sensors, an MQ-2 and MQ-4. These sensors are used as a proof of concept. They are meant to detect different chemicals in the air in order to understand whether there is smoke or dangerous chemicals in the air.
