Can a remote control be used long-term in humid environments?

Detailed Answer

Yes (with the right model). Key points for humid environments (southern plum rain season, seaside, underground garages): 1. Protection IP67 (LIDER LD series) or IP68 (XINGJIA Xingdun); 2. Conformal-coated circuit board (moisture and corrosion resistance); 3. ePTFE breathable membrane (condensation prevention); 4. Regular drying (store in a drying box / power on to remove moisture). Don't use models below IP54 in humid environments — internal condensation shorts are a common failure.
