#How does it work?
# 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.
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.
