How expensive would it be to make a machine that can smell if you or your clothes stink?
I would pay at least $150 for that as a hard-of-smelling person. I would have far paid more back when I was single and lonely.
- Mo3 10y agoYou can do this for farts already with a Raspberry Pi and a gas sensor, maybe there's other types of sensors that can detect ammonia? https://www.raspberrypi.org/learning/fart-detector/worksheet/ https://www.raspberrypi.org/learning/fart-detector/worksheet...
- maxxxxx 10y agoI would like that too. After a surgery a few years I sometimes have post nasal drip which causes bad breath. I have no way to tell when this happens. I would love a sensor that could detect it.
- afarrell 10y agoAccording to your sibling, there are already off-the-shelf sensors that detect some malodors. Maybe we just need to source already-existing components and convince an EE/manufacturing engineer to do a kickstarter?
- maxxxxx 10y agoThe problem is that you need to know what chemical you are looking for that's causing the smell. Are there any sensors that can detect a wide range of smells?
- jonwachob91 10y agoA quick google search reveals a number of label free odor sensors, everything is early stage though. Label free may not be the best phrase for what you meant though. Label free means you are looking at all biomarkers present in a sample, the primary challenge with label free is that we don't know every biomarker to look for or what every biomarker we see means.
- maxxxxx 10y agoSeems once you have enough datapoints you should be able to do something with machine learning to distinguish good from bad smells.
- easilyBored 10y agoHow expensive would it be to make a machine that can smell if you or your clothes stink? Wash them at least twice a year :) . Bad breath I can understand, you can't tell at times but clothes? Just wash them...
- ghthor 10y agoI hope you're joking. You should be washing them after 1 day of wearing, maybe even less.
- easilyBored 10y agoHalf joking. No, jeans don't need to be washed after every time. Nor do sweaters or jackets. Underwear, t-shirts and socks are different. This is my rule anyway
- zamalek 10y agoThe real problem is replicating our olfactory system. It can detect millions of compounds (even undiscovered and new) and we still have competing theories on how it works. One involves quantum mechanics[1], which is very hard to replicate with our current level of manufacturing.
