1. Introduction

HLK-LD2416 is a very small AIP human life presence sensor in the Hailingke 24G radar series, which includes extremely simplified 24GHz sensor hardware 2416 and human presence sensing intelligent algorithm firmware, capable of detecting sitting and lying human bodies.

The hardware HLK-LD2416 is equipped with an ICL111AAIP millimeter wave sensor, a high-performance 24GHz one transmitter one receiver antenna, and peripheral circuits, as well as an AIP chip

Line embedding, no need for high-frequency boards, faster processing. The human presence sensing algorithm adopts millimeter wave sensor distance measurement technology and S1 series chip proprietary technology. The advanced radar signal processing technology enables precise perception of motion, micro motion, and sitting still. The firmware of the intelligent algorithm for human presence sensing is mainly used in indoor scenes are used to perceive whether there is motion, micro movement, or the presence of human bodies in the area, and to refresh the detection results in real time.

The maximum sensing distance of HLK-LD2416 for a moving human body is 7.5m, and the sensing distance range, triggering and holding thresholds for different intervals can be easily configured. And no one reported the time. HLK-LD2416 supports GPIO and UART interfaces, plug and play, and can be flexibly applied to different intelligent scenarios and terminal production

Product. Simultaneously supporting automatic generation of detection thresholds, reducing manual debugging, improving detection accuracy, simplifying installation processes, and facilitating large-scale deployment.
