The Hi-Link HLK-LD2402 is an advanced 24GHz millimeter-wave (mmWave) human presence radar sensor module engineered for indoor occupancy and motion detection. Leveraging FMCW (Frequency Modulated Continuous Wave) radar technology, the HLK-LD2402 precisely detects human motion, micro-motion, and stationary presence with high sensitivity and stability.
Unlike conventional PIR sensors, this mmWave radar sensor can detect static human presence, making it ideal for applications that require continuous awareness rather than simple motion triggers. With configurable sensing parameters and support for both UART and Bluetooth configuration, users can easily tailor detection distance, sensitivity, and delay times to match their specific use case.
