Project Proposal Guideline

Introduction

Statement of Purpose

Our project is quite simply, a system that will detect the overwhelming presence of a gas other than oxygen and then will activate fans to both vent the room of gas and blow fresh air into the room.

Background Research

Carbon Monoxide is an odorless gas that humans with natural senses can not detect. Hundreds of people fall to carbon monoxide poisoning and this a problem that could be avoided. If a simple air exchange unit system was implemented, countless lives would be saved. This solution would not only work for carbon monoxide, but any deadly gas that one could not see.

What exactly is the arduino doing for your project? If you are just checking sensor readings, an arduino seems like a lot of overkill. Also, I suggest doing some background research into determining how much air flow it takes for a given area (number of fans, size, speed, etc). Also keep in mind that similar to running a motor directly off of an arduino (you should see this in 110 lab) is ineffective because an arduino's pins are very low power, so you all will need some other component to build your fan drive circuits.

Don't forget that you will need to use a logic element for the ECE120 requirement. Could you discuss an implementation of a logic element in your proposal (maybe add one more feature that could make use of it). Once you've updated that, I should be able to approve your project.

I like the concept and safety design.  Going along with what Alonzo said, make sure you do a bit more research into what specific parts you'll need, how they'll connect, and their requirements.
