HLK-LD2402 24GHz Radar Motion Detection Sensor Module
HLK-LD2402 24GHz Radar Motion Detection Sensor Module
The HLK-LD2402 24GHz Radar Motion Detection Sensor Module is a moving and stationary human body detection sensor. It operates at 24GHz frequency and can detect up to 7 meters. It has a low energy consumption of 50mA. The simplified 24GHz sensor hardware has intelligent algorithm software for micro-movement of the human body. It is equipped with a high-performance 24GHz single transceiver antenna and peripheral circuitry. It is used to detect whether a human body is moving indoors, its micro-movement, or its presence, and to update the detection results in real time.
The HLK-LD2402 supports GPIO and UART interfaces. It operates on a plug-and-play principle. It reports the measurement result in real time. It supports multiple mounting modes such as ceiling and wall mounting. It automatically turns on when a person arrives and automatically goes into sleep mode when no one arrives; Thus, energy is saved.
