1. Introduction

HLK-LD2412 is a highly sensitive 24GHz human presence state sensing module developed by HI-LINK Electronics. Its working principle is to use FMCW frequency modulation continuous wave to detect human targets in the set space, combined with radar signal processing and precise human body sensing algorithms, to achieve high sensitivity human body presence state sensing, recognize human bodies in both moving and stationary states, and calculate auxiliary information such as target distance. This product is mainly used in indoor scenes to perceive whether there is movement or micro movement of the human body in the perception area, and to output real-time detection results. The farthest sensing distance can reach 9 meters, with a distance resolution of 0.75 meters. Provide visual configuration tools that can easily configure sensing distance range, sensing sensitivity in different intervals, and unmanned delay time to meet different specific application requirements.

Supports GPIO and UART outputs, plug and play, and can be flexibly applied to different intelligent scenarios and terminal products.
