I am not aware of a good and low-cost wifi connected sensor but as I mentioned it is relatively easy to build one yourself.
If you don't want to buld yourself, there are a few relatively good non-connected PM 2.5 sensors for example the "SmartMi PM2.5 Air Quality Monitor" that I can recommend. It costs around USD 30 here in Asia.
