4X 24Ghz Human Presence Sensor Module TTL Serial Communication LD1115H Micro-Motion Detection

4X 24Ghz Human Presence Sensor Module TTL Serial Communication LD1115H Micro-Motion Detection Popis

Introduction
HLK-LD1115H is a high sensitivity 24GHz millimeter wave human presence detection module. The main feature of this module is that the basis of the function of the traditional human body induction , it also has the function of judging the existence of the human body by detecting and accumulating small movements such as human breathing.
Therefore, the presence detection within a certain range has higher accuracy and is not easy to miss.
