Aqua Buddy was commissioned by RE-SET. A company that stands for sustainability. They wanted a solution for the fact that too many PET bottles are bought on the Amstel Campus.

Design Challenge

“How can an owner of a water bottle, with the help of an IOT solution, not forget to bring his water bottle, so that he does not have to buy a PET bottle.”

State 1: Connection between water bottle and key ring disconnected

You have a key ring and a band for your water bottle. These two are connected to each other by using Bluetooth. When the connection between the band and the key ring is disconnected, the key ring will vibrate. The key ring will vibrate in short bursts of 2 seconds with a 1-second pause in between.

State 2 : Keyring vibration

The vibrations will remind you that you forgot your water bottle. By pressing the button the key ring will stop vibrating.
