Main selling point still remains, being an ultra-sonic sensor, it overcomes the errors in reading from outside light and sound and that it could send out real time information to the cloud using any available infrastructure. It has the capability to store the data and send it across in batches (SD card on board, if need be).
As our team tested that, it can that it can be retrofitted in most coolers without much effort and cost, the manpower cost per cooler is almost negligible.
The model we displayed to the judges was working 100% and ready to go live on the final day. We took care to have no moving parts in our project, thus leaving no room for damaging it while restocking.
The costing of the product goes down to $5 (wholesale) per cooler, including man-power cost to get it in place, which is another great positive.
Have a quick look at the live video of how it works below: https://youtu.be/JD1E6LaMOZ8
Being a team that didn't know each other before the project, and being from completely varied background, it was a great achievement to accomplish this in couple of days (especially when you start from scratch)
