Smart bath fan

We have the technology

All this talk about bathroom fans with timers, motion sensors, flush-detectors... Why not just make a bathroom fan that can detect the distinctive odours of poop and/or farts, and that runs until they're gone? We have the technology.

We've been at this so long, I realize there's a big chance this, and any other ideas I could cook up, will have been "baked". I had to vent my thoughts, though.

       It will need an "acceptable minimum" rather than "zero" to stop. Apparently, there's fecal matter floating around everywhere (in tiny amounts...).
Also, linky.

       It is being worked on [link], but hardly widely known to exist so... (+)   

       Uh huh. Fess up. Were you 'actually' aware that this product existed before [Ander] posted this or did you look it up after the fact?   

       [a1]; "years" is a bit of a stretch. The article you linked is only from 2019!

       Objection! Prosecution is leading the jury.   

       Kidding. I just contend that widely-known-to-exist might be a stretch.   

       Agreed. I've never heard of them. Then again, I'm not often in the bathroom fan market. But as often as I use it, you'd think I'm the 95th percentile customer...

       I do believe that that mind-set will discourage innovation.   

       I've independently thought up many inventions which have been thought up by others previously, but posted them to find out if they exist.   

       My gut didn't tell me that this already existed, and my own personal experience didn't tell me that this already existed.   

       So... in my own mind only... it's not widely known to exist and I am happy to be exposed to its existence.   

       That would have not happened otherwise... so...   

       ....(+) from me.   

       I like to believe that I know about a fair number of things which are 'widely known.' Especially as I've been in a bathroom or two in my life. No, I didn't Google it, but also no, I'm also not one to rush to judgment on ideas posted from less frequent users, and this isn't a court case, so...

       Whatever. "Oh no! The wall has been breached by nonoriginal ideas! Fall back! Fall back to the Keep!"

       ^^Maybe, the new silicon wafers, can calculate needed the ratio.
