1. Module Appearance and Interface
HLK-LD1125H-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 to judge the existence of the human body by
detecting the accumulated human breathing and other small-scale movements. Therefore, the
detection of human presence is more accurate than traditional mobile detection radars. Not easy
to miss.
