Features: Strong anti-interference: 5.8GHz working frequency is adopted, which is less affected by external environmental factors, ensuring stable and reliable performance. Automatic metering: Automatically detects ambient light levels and turns on the light when lighting conditions require and motion is detected. Otherwise, the light remains off. Equipped with dial switches for adjustment, offering high accuracy, low error rate, easy setting, and long service life due to oxidation-resistant contacts. Uses solderless, untwisted wires with press-type wiring terminals for convenient and secure installation. Compatible with switches and lighting fixtures, supports LED, energy-saving, and incandescent lights. Suitable for bathrooms, stairs, rooms, corridors, and similar areas.
