LD2410C 24GHz Radar Human Presence Sensor Module Product Overview The HLK-LD2410C is a high-sensitivity 24GHz millimeter-wave radar human presence sensing module developed by Hilink Electronics. Based on FMCW (Frequency-Modulated Continuous Wave) radar technology, it combines radar signal processing with an accurate human body detection algorithm to achieve reliable human presence sensing. The module can identify both moving and stationary human bodies, including micro-movements, and can calculate auxiliary information such as target distance. It is designed primarily for indoor applications, providing real-time detection results with flexible configuration to meet different scene requirements. Key Features Plug-and-play design for easy assembly High-sensitivity 24GHz radar sensing Detects moving and stationary human presence, including micro-motion Maximum sensing distance up to 6 meters Distance resolution of 0.75 m Effective sensing distance commonly up to 5 meters Wide detection angle of ±60° Supports segmented sensing ranges and interference shielding outside defined intervals Multi-level intelligent parameter adjustment for different environments Visual debugging and configuration tool Supports GPIO and UART output Compact size: 22 × 16 mm (0.86 × 0.63 in) Supports ceiling and wall mounting Operates in the 24GHz ISM band, compliant with FCC and CE spectrum regulations 5–12V wide-voltage power supply Cost-effective solution for human presence detection Benefits Detects not only moving people, but also static, micro-moving, sitting, or lying human bodies that traditional solutions may miss Stable performance unaffected by environmental factors such as temperature, brightness, humidity, or light changes Strong shell penetration allows concealed installation without surface openings, improving product aesthetics Flexible configuration of sensing distance and sensitivity for each distance interval, enabling fine-grained personalization Technical Specifications Parameter Details Model LD2410C Sensing Technology 24GHz FMCW millimeter-wave radar Maximum Sensing Distance Up to 6 m Effective Sensing Distance Up to 5 m Distance Resolution 0.75 m Detection Angle ±60° Output Interfaces GPIO, UART Power Supply 5–12V Band 24GHz ISM Compliance FCC, CE Size 22 × 16 mm (0.86 × 0.63 in) Material PTFE Color As shown Package Contents 1 × LD2410C 24GHz Radar Human Presence Sensor Module Application Scenarios Designed for indoor environments requiring reliable human presence sensing and real-time detection feedback.
