1.2.Application Scenarios

HLK-LD2420 human body sensing sensor can detect and identify moving, standing and

stationary human bodies, and is widely used in various AIoT scenarios, covering the following types.

Smart Home

It senses the presence and distance of the human body and reports the detection results for

intelligent control of home appliances by the main control module.

Smart Business

Recognizes the human body approaching or moving away within the set distance interval; lights

up the screen in time to keep the device on in the presence of the human body.

Smart Security

Induction access control, building intercom, electronic cat's eye, etc.

Smart Lighting

Identify and sense human body, precise position detection, can be used in public place lighting

equipment (sensor lamp, bulb lamp, etc.).

HLK-LD2420 is an intelligent and accurate human sensor based on Hylink S3 series millimeter

wave sensor chip. The sensor uses FMCW FM continuous wave, combined with radar signal

processing and built-in intelligent human sensing algorithm to detect human targets in a set space and

update the detection results in real time. Using Haling Technology's intelligent millimeter wave

sensor reference solution, users can quickly develop their own accurate body sensing products.

The hardware part of HLK-LD2420 is composed of a fully integrated Hylink Smart Millimeter

Sensor SoC, a 24 GHz transmitter-receiver antenna and a host MCU; the software part is equipped

with firmware and visual configuration tools released by Hylink to realize human body sensing

functions with flexible configuration of sensing distance, sensitivity and reporting time.
