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.).
2. System Description
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.
