The Eforthink Lightweight and Multi-functional Positioning Tag (Intrinsically Safe Version) is a cutting-edge Personnel Location Tag designed for integration with RTLS (Real Time Location System) technologies. As a core component of the Henggao Positioning System, this intrinsically safe device is engineered for personnel tracking in explosive environments. Combining UWB location technology, AOA, and iBeacon positioning modes, it delivers centimeter-level precision—a hallmark of advanced RTLS Technology. The tag also leverages Zigbee communication in the 900MHz band to enhance data transmission reliability, ensuring seamless integration with real-time location tracking platforms. Key functionalities include real-time safety alerts for boundary breaches, proximity to hazards, or unauthorized activities, as well as an SOS distress signal that triggers immediate system notifications for rapid rescue coordination. Built for industrial rigor, this location finding device supports dynamic scenarios requiring real-time location tracking, such as emergency response, hazard avoidance, and workforce optimization.
