Product Introduction
HLK-LD2410D is a static human life presence sensor developed based on Hi-link millimeter wave sensor chip. sensing the device adopts FMCW frequency modulation continuous wave, combined with radar signal processing and built-in intelligent human body induction algorithm, to detect the noise in the set space detect human targets and update detection results in real-time. Using HLK-LD2410D, users can quickly develop their own precise human body presence sensing products.
The hardware mainly consists of a fully integrated intelligent millimeter wave sensor SoC, a 24GHz transmitter receiver antenna, and a main control MCU; the software is paired with intelligent human body presence sensing firmware and visual configuration tools to achieve flexible configuration of sensing distance, triggering, and other functions maintain human body sensing function for threshold and unmanned reporting time.
