Upgrade your bathroom mirror with this YZKJ-LD-FT Premium Radar Motion Sensor Switch, featuring advanced radar technology for automatic LED light control. Specially designed for smart LED mirrors, vanity mirrors, and mirror cabinets where hands-free operation is desired.
This premium sensor switch uses microwave radar detection technology to sense human presence, automatically turning lights on when you approach and off when you leave. Unlike traditional PIR sensors, radar technology detects movement through glass, acrylic, and even thin panels, making it perfect for concealed installations behind mirrors.
With radar motion detection, it supports:
• Automatic ON when human body detected within range
• Automatic OFF after adjustable time delay when no movement detected
• DC12V input for flexible installation
• 60W power capacity (5A) for bright mirror lighting
• Adjustable sensitivity and time delay settings
• Works through glass, acrylic, and non-metal surfaces
• Premium quality construction for long-lasting performance
