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? | ||
