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.).
