The eWaft system aims to create a realistic means of food monitoring to prevent wasted resources like time and money spent on groceries. It uses ionized emitted vegetation vapors detected by a voltage drop across a sensor that is transmitted to an interactive Android tablet displaying parts per million and ripeness estimation. The system could provide a permanent integration into modern food storage and easily integrate with mobile devices. However, the science behind the project required significant learning and challenges included properly managing time to allow for problem solving.

2. In a Nutshell…

3. We aim to create a realistic means of
food monitoring for the prevention of
wasted recourses.
-Time
-Money
-Groceries
The eWaft is designed for a wide range of people: Anyone who eats
Upon the completion of our system, it could be a permanent
integration of todays food storage.
With the large market to mobile device users, integration to two
well established institutions would be easy.

4. Original Idea Todays Change
-Sensing nodes in -Home food storage
shipping containers sensing
-Wireless transition -Android interactive
to driver display
-Prevent spoiled -Prevent food
food from causing wasting
further
damage

5. In Short…
The eWaft ionizes emitted vegetation vapors
that can be detected as a drop across a voltage.
That voltage is transmitted via a AOC using CAN
to an mobile tablet for a parts per million
conversion and ripeness estimation.
…Uhh…What?
The eWaft senses gasses from fruit and displays
the information on an interactive android
screen.

6. Contributions:
The android accessory kit comes with source code
and demos for simple implementation of its
features.
Those have been heavily modified and added too.
The Figaro sensor have suggestions and test
scenarios.
We took „suggestions‟ quite literally

7. Road Blocks?... Yup
Corey -> The Science. Cross Field Projects
require a lot of time to learn what you don‟t
know. “I refuse to move on with the project if
it works but I don‟t understand why” –Me
Chris -> New concept on Time management.
Ordering parts much earlier in advance to give
more time to problem solving later.

8. WE are pleased
We have Learned so much but there is much more
to do... Much more to figure out.
