24G Microwave Human Presence Radar Sensor (AC100-250V Version)
Product Introduction
The millimeter-wave radar human presence sensor is based on 24G microwave technology, actively detecting subtle movements such as human breathing, slight movements, and human motion. It can accurately detect the presence or absence of people in the area, as well as the state of a person being stationary or sleeping, recognizing static human presence, ensuring the light stays on when someone is present.
This product is widely used in smart homes, smart hotels, smart offices, security monitoring, smart parking, and other IoT fields, providing sensing and scene linkage functions. Active DC Version is commonly used for smart lighting.
