1. Product introduction

Motion target tracking is to track the position of the moving target in the region in real time, and realize the distance, angle and speed measurement of the moving target in the region.The LD2450 is a motion target tracking sensor module from the Hilink 24G millimetre wave radar series, which includes extremely simplified 24 GHz radar sensor hardware and intelligent algorithm firmware. The solution is mainly used in general indoor scenarios such as homes, offices and hotels to enable the location tracking of moving human bodies.

The sensor hardware consists of an AloT millimetre wave radar chip, a high performance one-transmitter-two-receiver microstrip antenna and a low cost MCU and peripheral auxiliary circuitry. The intelligent algorithm firmware uses FMCW waveforms and the radar chip’s proprietary advanced signal processing technology.

It supports serial output of detection data, which is plug-and-play and can be flexibly applied to different smart scenarios and end products.

2. Product Features

3. Solution advantages

LD2450 human body sensing module adopts 24GHz millimeter wave radar sensor technology, compared with other programs, has obvious advantages in human body sensing applications:

1. In addition to sensitive sensing of the movement of the human body, for the traditional program can not identify the micro-movement of the human body can also be sensitive to sense;

2. Good environmental adaptability, the induction effect is not affected by the surrounding environment such as temperature, brightness, humidity and light fluctuations;

3. Good shell penetration, can be hidden inside the shell work, no need to open holes in the product surface, improve the product aesthetics;

4. Application scenarios

The LD2450 motion target tracking sensor can accurately locate and track targets and is widely used in various AloT 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 air conditioners, fans and other home appliances.

Smart Business

Position sensing, within the set position interval to identify the human body approaching or moving away, timely lighting or closing the screen.

Bathroom

Smart toilet accurately controls the automatic opening and closing of the toilet lid.

Smart Lighting

Identify and sense the human body, precise position detection, can be used in home lighting devices (sensor lamps, desk lamps, etc.).
