Might be able to use a flipper zero as the sensor, if the cats are chipped. Then you'll have data to catch any unusual usage, like a urinary blockage, before it becomes a serious problem! At that point you're a smart switch and Home Assistant script away from fan control.
I would recommend to use an TVOC sensor that detects smell very easily and then automatically switch on a fan. Could be a fun project.
Just need: - TVOC sensor like the SGP41
- ESP32 microcontroller
- Electric Relay
I’m highly unimpressed by my couple of SGP41 sensors, but they would probably work for this application.
Interesting idea. Do TVOC respond with enough signal to low level aromatics verses all the particles from cooking or pollution?
Garply had a blockage once and he did a remarkably good job of communicating the problem to us directly!
As a fellow cat person, I feel pretty confident interpreting what’s being implied here. :-)
Beautiful home and contents, btw! It seems expensive but more than a few folks would have spent the same money on “nicer marble” or something.
Heh, I actively dislike "nice marble" or anything that just looks expensive without providing any functional benefit.
I did wonder where the network connections were going into the cat areas!
