Description
The Hi-Link HLK-LD2401 is an advanced 24GHz millimeter-wave (mmWave) human presence radar sensor module developed for reliable indoor occupancy and movement detection. Powered by FMCW (Frequency Modulated Continuous Wave) radar technology, the HLK-LD2401 delivers high sensitivity and precision, enabling it to detect both human motion and stationary presence.
Unlike conventional PIR sensors, this mmWave radar sensor can continuously sense static human presence, making it ideal for applications that require intelligent and responsive control. With support for UART and Bluetooth configuration, users can easily adjust sensing distance, sensitivity, and delay parameters to suit specific environments and use cases.
