#How does it work?

Sonar

# What does it measure?

Objects in between sensor and opposing side of cooler. The height can be adjusted to ignore sandwiches / other objects.

Does the retailer/bottler/distributor have to do anything different to make your solution work? (if yes, please explain)

Install sonars / logic board. The communication from retailer to Coke headquarters was intentionally left unapproached. This approach is a retailer <-> Coke solution. The bottler / distributor are not included.

What materials does your solution require?

logic , sonars, logic / sonar connection

Best guest on cost to implement

<$20 at retail from amazon. Scaling up to the tens of millions should be cheaper as I have not unleashed near the full power of these retail parts

Challenges you/your team ran into

The cheap sonar sensors had a large blind spot. I put a sonar on each side of the row and triggered them sequentially instead of concurrently so that there is no way the sound would interfere. I am operating at the speed of sound, so I can easily trick a human into thinking they are concurrent.

What you/your team learned

It is easy to fry an arduino.

Next steps

Testing for animals. I like dogs and fear that these cheap sensors might be noticeable to some animals. The frequency of the sonar is a variable. Selecting the correct frequency should be a serious consideration.

Anything else you want to add

This environment was more cooperative than similar events. This one was much more social. More enjoyable.
