The Hi-Link HLK-LD2450 is a compact 24GHz mmWave radar sensor module designed for indoor human motion tracking and presence detection. It can detect and track moving targets in real time, providing distance, angle, position, and speed data through serial output.
The module is suitable for smart home projects, Home Assistant sensors, ESPHome builds, lighting automation, occupancy detection, security projects, and other IoT applications where radar-based motion tracking is preferred over traditional PIR sensors.
This version includes the connection cable, making it easier to connect the module to ESP32 boards, microcontrollers, and custom electronics projects.
