Introduction

HLK-LD1125H-24G is a high sensitivity 24GHz millimeter wave human presence detection radar module. The main feature of this module is to judge the existence of the human body by detecting and accumulating tiny movements such as human respiration. Therefore, the detection of human presence is more accurate than traditional mobile detection radars. Not easy to miss
