HLK-LD2412 is a highly sensitive 24GHz human presence state sensing module developed by HI-LINK Electronics. Its working principle is to use FMCW frequency modulation continuous wave to detect human targets in the set space, combined with radar signal processing and precise human body sensing algorithms, to achieve high sensitivity human body presence state sensing, recognize human bodies in both moving and stationary states, and calculate auxiliary information such as target distance.
