The Hi-Link HLK-LD2410D is an advanced 24GHz millimeter-wave (mmWave) human presence radar sensor module developed using Hi-Link’s intelligent radar sensor chip and embedded human-body detection algorithms.
By adopting FMCW (Frequency Modulated Continuous Wave) radar technology, combined with radar signal processing and intelligent induction firmware, the module accurately detects human motion, micro-motion, and static presence within a defined sensing area and updates detection results in real time.

Unlike PIR sensors, the HLK-LD2410D can reliably sense stationary humans, making it ideal for applications that require continuous occupancy awareness. With plug-and-play default configuration, adjustable sensing distance, configurable disappearance delay, and strong anti-interference capability, users can rapidly develop precise human presence sensing products.
