1. Product Overview

Target tracking refers to real-time tracking of the location of a target within an area, achieving distance measurement, angle measurement, and speed measurement of the target. HLK-LD2452 is a high-precision multi-target recognition sensor, which is mainly applied in ordinary indoor scenes such as homes, offices, and hotels to achieve positioning and tracking of multiple human bodies. The sensor hardware consists of an AIoT millimeter wave radar chip, a high-performance one transmitter two receiver microstrip antenna, a low-cost MCU, and peripheral auxiliary circuits. The intelligent algorithm firmware adopts advanced signal processing technology proprietary to FMCW waveform and millimeter wave radar chips

3. Application

The HLK-LD2452 multi-target recognition sensor can accurately locate and track human targets, and is widely used in various AIoT scenarios, covering the following types: 

• Smart Home 

 Sensing the distance and angle of the human body, reporting the detection results for the main control module to intelligently control the operation of household appliances such as air conditioners and fans; 

•  Intelligent Business 

 Position sensing, recognizing human proximity or distance within a set location range, and promptly turning on or off the screen; 

•  Bathroom 

 Intelligent toilet accurately controls the automatic opening and closing of the toilet seat; 

•  Smart lighting 

 Identifying and perceiving the human body, precise position detection, can be used for home lighting equipment (induction lamps, desk lamps, etc.)
