Application
🔦 Smart Lighting Control
Automatically detects whether someone is present in the space and controls lighting accordingly — ideal for public areas, sensor-based lamps, bulb lights, and energy-saving lighting systems.
🖥️ Intelligent Wake-Up for Displays & Devices
Activates advertising screens and other equipment when people approach, and enters sleep mode when no one is nearby — saving power while ensuring timely and efficient information delivery.
🛡️ Life Safety Protection
Prevents UV lamps from operating when people are present, avoiding accidental exposure and injury. Enables automatic detection and alerting in hazardous zones to prevent unauthorized entry — especially useful in high-risk areas like coal mine blasting zones.
🏠 Smart Home Appliance Management
Automatically powers off TVs, air conditioners, and other appliances when rooms are unoccupied for extended periods — enhancing both energy efficiency and safety.
🔐 Intelligent Security Monitoring
Detects and identifies human presence, intrusion, or lingering within designated areas — supporting advanced security and surveillance systems.
