    HLK-LD2401 24GHz Human Presence Radar Sensing Module with Bluetooth Support

    RBD-3791
    Hi-Link

    The HLK-LD2401 is a high-sensitivity 24GHz FMCW millimeter-wave radar sensor module developed by Hi-Link Electronics. Designed for human presence detection, it can accurately recognize both motion and micro-movements (such as sitting, lying, or slight gestures) within its sensing area. Unlike traditional PIR sensors, the LD2401 performs reliably even in challenging environments with varying temperature, brightness, humidity, or lighting conditions.
