Hi-link HLK-LD2460 24Ghz Human Motion (5p) Tracking Radar Sensor Module

The Hi-Link HLK-LD2460 is a high-performance 24GHz millimeter-wave (mmWave) radar sensor module designed for human motion detection and multi-target tracking. Built on a dual 1T2R (one transmitter, two receivers) radar architecture, the HLK-LD2460 delivers enhanced spatial resolution and accurate tracking of up to 5 moving individuals within its sensing area.

Using advanced radar signal processing, the module accurately determines distance, angle, and movement of human targets, making it ideal for smart homes, offices, hotels, and elderly care environments. Unlike camera-based systems, radar sensing preserves privacy and operates reliably regardless of lighting conditions.

With wide horizontal and vertical coverage, fast detection times, and support for over-the-air (OTA) firmware updates, the HLK-LD2460 is well suited for scalable and future-ready smart sensing solutions.
