Wardrobe sensor lights provide automatic illumination for almirahs, kitchen cabinets, drawers, and walk-in closets. Single-door IR sensors suit individual cabinets, while dual-door sensors activate lighting when either door opens. Battery-operated hinge lights offer a convenient, wiring-free retrofit. Hardwired sensors typically operate on 12V/24V DC and detect door movement within 5–6 cm. These systems improve visibility, convenience, and energy efficiency.
