Hi-Link/HLK-LD1115H-24G human presence sensor micro-motion detection mobile sensor radar module TTL serial communication -84359

HLK-LD1155H-24G is a high sensitivity 24GHz millimeter wave human presence detection radar module. Different from the traditional radar, which judges the existence of the human body by detecting the large-scale movements of the human body or the small-scale body movements, the main feature of this module is that on the basis of the function of the traditional human-body induction radar, it also has the ability to detect and accumulate small-scale movements such as human respiration. , to determine the function of the existence of the human body. Therefore, compared with traditional Doppler radar, it has presence detection within a certain range, with higher accuracy, and is not easy to miss reports.

Modules can penetrate non-metallic enclosures without openings. Common materials include plastic, glass, wood, ceramic, and more. Especially for human presence detection applications, wall-mounted plastic 86-box panels and ceiling-mounted ceiling buckle enclosures are recommended.
