HLK-LD8001B/H, LD7901:














HLK-LD2410S is a battery powered ultra-low power millimeter wave sensor for human presence in the Hi-Link LD2410S series, including extremely simplified 24 GHz Millimeter wave sensor hardware LD2410S and low-power human presence sensing intelligent algorithm firmware.

The hardware LD2410S is equipped with AIoT millimeter wave sensors, high-performance 24 GHz 1T1R antenna, and peripheral circuits; Low power intelligent human body sensing the algorithm adopts millimeter wave sensor distance measurement technology and advanced proprietary radar signal processing and low-power control technology of ICL1112 chip to achieve motion accurate perception of micro motion and standing human body. The low-power human presence sensing algorithm firmware is mainly applied in indoor scenes, and the low-power mode is used to perceive the presence of whether there is movement or micro movement of the human body, real-time refresh of the detection results.

The maximum sensing distance of HLK-LD2410S to a moving human body is 8M, with different triggering and holding thresholds, human presence status, and target human body in different intervals distance reporting frequency and unmanned reporting time. 

HLK-LD2410S supports GPIO and UART interfaces, plug and play, and can be flexibly applied to different intelligent devices capable of scenario and terminal products.
