HLK-LD2410S Microamp Low Power Radar Sensing Module
Important Notice: This product is shipped from China to our Munich warehouse before final dispatch. Estimated processing time: 2 weeks. Thank you for your patience!
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, a 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 micromotion and the 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 for a moving human body is 8M. It has different triggering and holding thresholds, human presence status, and target human body distance reporting frequencies in different intervals and unmanned reporting times.
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.
