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?
