Help detecting hand washing
Hello,
this might be a weird request, but I'm immunocompromised and I'm sure my mother doesn't wash her hands after using the bathroom (even poop yes).
Since moving out is not an option and trying to explain to her for the thousand time that not washing her hands puts me at danger, I came here asking for help.
I want to know which sensors can I use to detect: if someone pushes the flush,then uses the garbage bin and doesn't open the faucet.
I've never used sensors, but played around with raspberries .
Any ideas and suggestions are appreciated.
Thank you
