No matter who you are, you produce garbage of some kind or another. Two students decided they wanted to create a smart garbage can that could alert them when the can is full or even when it is stinky.
We will go on on the record: we didn’t know that an alcohol sensor could tell if your garbage is stinky, so if that works, that’s a new one on us. However, it makes a certain kind of sense because garbage ferments. We thought garbage smelled because of hydrogen sulfide and methane.
Trash cans have a tough life, so if you really want to duplicate this, you’ll probably want to mount things a bit more securely. The software, however, runs everything through a cloud service and from there can use Blynk for a phone app and IFTTT to ship things to a spreadsheet, should you care to track your garbage history statistics.
You can see in the video this is a small proof of concept can. We almost want to build one just to see if the sensor really knows when the can is smelly.
Granted, the project may not be the most practical, but it is amazing how easy it is now to build devices with a high degree of connectivity thanks to the wealth of inexpensive boards and services available.
