Enhance recycling with the Arduino Professional Portenta C33 and AI audio classification

Arduino GroupNovember ninth, 2023

In July 2023, Samuel Alexander got down to scale back the quantity of trash that will get thrown out on account of poor sorting practices on the recycling bin. His authentic design relied on an Arduino Nano 33 BLE Sense to seize audio by means of its onboard microphone after which carry out edge audio classification with an embedded ML mannequin to mechanically separate supplies primarily based on the sound they make when tossed inside. However on this newest iteration, Alexander added a number of massive enhancements to assist the idea scale a lot additional.

Maybe essentially the most substantial modification, the bin now makes use of an Arduino Professional Portenta C33 together with an exterior Nicla Voice or Nano 33 BLE Sense to not solely carry out inferences to type trash, but additionally ship real-time information to a cloud endpoint. By using the Arduino Cloud by means of the Portanta C33, every AI-enabled recycling bin can now report its present capability for every sort of waste after which ship an alert when assortment should happen.

Whereas not as sensible for family use, this integration may very well be extremely efficient for municipalities trying to create a community of bins that may be deployed in a metropolis park surroundings or one other public house.

Thanks to those upgrades, Alexander was capable of submit his prototype for consideration within the 2023 Hackaday Prize competitors the place he was awarded the Protolabs manufacturing grant. To see extra about this modern venture, you possibly can take a look at its write-up right here and watch Alexander’s detailed clarification video under.
