HLK-LD1125H-24G
HLK-LD1125H-24G is a high sensitivity 24GHz millimeter wave human presence detection radar module. Different from traditional radar through detect the large-scale movements of the human body or the small-scale body movements to determine the existence of the human body. The main feature of this module is to detect the tired human breathing and other small-scale movements to determine the existence of the human body.
