Q & A

The HLK-LD2410B is a high-sensitivity 24 GHz human presence radar module from Hilink Electronics. Using FMCW (Frequency-Modulated Continuous Wave) technology and advanced radar signal processing, it accurately detects both moving and stationary human targets.

It can calculate auxiliary data, such as distance, supporting a maximum sensing range of 5 meters with 0.75-meter resolution. Designed for indoor applications, the module identifies motion and micro-movements, providing real-time detection output.

A visual configuration tool allows easy adjustment of detection range, sensitivity in different zones, and unmanned delay time, making it adaptable to various bright lighting, security, and automation systems.

Features:

Detection Range: The module can detect human presence at distances up to 5 meters, with a resolution of 0.75 meters, ensuring high precision.
Wide Detection Angle: The sensor covers a ±60° field of view, allowing it to monitor a broad area.
Micro-Motion Detection: In addition to detecting moving human bodies, the module can detect static and micro-movements, such as sitting or lying down.
Adjustable Sensitivity: Users can fine-tune detection parameters to suit specific needs.
Bluetooth & UART Communication: The sensor supports Bluetooth and UART interfaces, enabling flexible configuration via mobile apps or direct device integration.
Strong Environmental Adaptability: The sensor operates effectively across a wide range of environmental conditions, unaffected by factors such as temperature, humidity, and light.
Compact Design: The module is tiny (7mm x 35mm), making it easy to integrate into various devices such as smart home systems or security devices.
