HRGXYUN Radar Motion Sensor for Stair Lights - Vertical Detection Tech, Anti-Interference, Invisible Installation, Stable Triggering for Step Lighting Solutions

["1.Exclusive upward-facing radar technology detects movement ONLY when stepping directly on stairs, eliminating false triggers from nearby movement (e.g., living room activity). Ensures lights activate precisely when needed.","2.Unlike infrared sensors (affected by temperature/light changes), our radar system ignores ambient heat, sunlight flashes, door vibrations, and accidental wire contact – critical for reliability in unstable environments.","3.Low-profile design with industrial-grade adhesive tape enables invisible mounting under stair lights (center position recommended). No drilling, wires, or bulky hardware","4. Activates lights only during actual stair use, reducing power waste vs. constant-on solutions. Ideal for night-time safety on stairs and hallways without disturbing sleep cycles",""]
