No matter who you are, you produce trash of some kind or another. 2 students decided they wished to create a wise trash bin that might inform them when the can is fullor perhaps
when it is stinky. We will go on the record: we didn’t understand that an alcohol sensing unit could inform if your trash is stinky, so if that works, that’s a new one on us. Nevertheless, it makes a particular sort of sense since trash ferments. We thought trash smelled due to the fact that of hydrogen sulfide and methane.
Trash bin have a difficult life, so if you truly want to replicate this, you’ll most likely want to install things a bit more safely. The software, however, runs whatever through a cloud service and from there can use Blynk for a phone app and IFTTT to ship things to a spreadsheet, must you care to track your garbage history statistics.
You can see in the video this is a small proof of idea can. We almost want to construct one just to see if the sensing unit actually understands when the can is foul-smelling.
Given, the task may not be the most practical, however it is amazing how simple it is now to develop devices with a high degree of connectivity thanks to the wealth of low-cost boards and services readily available.
