24Ghz Human Presence Sensor Module TTL Serial Communication

Introduction
HLK-LD1115H is a high sensitivity 24GHz millimeter wave human presence detection radar module. 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 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.
