Hi-Link HLK-LD2460, 24GHz Trajectory Detection Radar Sensor

The Hi-Link HLK-LD2460 is a compact 24GHz radar-based trajectory detection sensor designed for precise motion tracking and presence detection. Unlike traditional PIR sensors, it uses millimeter-wave radar technology to accurately detect movement, track coordinates, and filter specific zones—even through obstacles like plastic or glass.

With configurable detection areas, multiple reporting formats, and high-speed UART communication, this module is ideal for smart automation, security systems, and human presence detection applications. Its ability to distinguish between regions and track motion trajectories makes it especially useful for advanced IoT and embedded projects.

Features:

1. 24GHz Millimeter-Wave Radar for accurate motion detection
2. Trajectory Tracking with X-Y coordinate output
3. Smart Zone Filtering (up to 3 configurable areas)
4. UART supports configurable baud rates from 9600–256000 bps; default baud rate is typically 9600 bps
5. Multiple Reporting Modes (presence, coordinates, or both)
6. Configurable via Serial Commands
7. Compact & Low Power Design for embedded systems
