How are fire detection mechanisms tailored for outdoor environments, particularly in small forest areas, given that most fire and smoke detectors are designed for indoor use?

Fire detection is a sort of broad idea. Usually people detect the products of fire, and most often this is smoke.
Many home fire detectors in the US use a radioactive source and measure the absorption of the radiation by the air. More smoke means more absorption.
For outdoor fire detection, PM2.5 can be a very good smoke proxy, and outdoor PM2.5 sensing is pretty accessible.
This one is very popular in my area.
