The HLK-LD2412 module utilizes Frequency Modulated Continuous Wave (FMCW) radar at 24GHz to penetrate common materials and detect subtle human movements and even stationary presence through micro-motions like breathing. Its advanced signal processing algorithms filter out environmental noise, providing reliable occupancy data for energy management and security systems.
Designed for indoor applications, the module outputs real-time target distance and motion state information. Its configurable parameters, including per-zone sensitivity and unmanned delay, allow for precise adaptation to specific room layouts and usage patterns, minimizing false triggers.
