Product Introduction LD2402 is Hi-Link stationary human life presence sensor, comprising extremely simplified 24GHz sensor hardware and human Body Micro-motion should be intelligent algorithm firmware. The hardware is equipped with AIoT millimeter wave sensor, high performance 24GHz one-and-receive antenna and peripheral circuit; The human body is sensitive. The algorithm adopts millimeter wave radar range measurement technology and advanced proprietary radar signal processing technology of radar chip to realize the detection of motion, Micromotion and precise perception of the presence of the human body. Human presence sensing intelligent algorithm firmware is mainly used in indoor scenes to sense the area Whether there is movement, micromovement or presence of the human body, and refresh the detection results in real time. The maximum sensing distance of HLK-LD2402 to the moving human body is 7m, and the sensing distance range and different intervals can be easily configured Trigger and hold thresholds and unreported time. HLK-LD2402 supports GPIO and UART interface, plug and play, It can be flexibly applied to different intelligent scenarios and end products. At the same time, it supports automatic generation of detection thresholds, reducing manual debugging Improve detection accuracy, simplify installation process, and facilitate large-scale deployment. Color: Blue Material: ABS Package Contents: 1 set of Human presence sensor Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
