HLKLD2410C 24G mmWave FMCW Human Presence Status Sensor Module Product overview This HLKLD2410C module is a 24 GHz mmWave FMCW motion and presence sensor designed for reliable human detection up to 5 meters. The module provides sensitivity detection with an attached cable for straightforward connection. It is intended as a stable electronic component for integration into automation, security, and IoT systems. Key benefits Accurate presence and motion detection: 24 GHz mmWave FMCW sensing detects movement and presence with fine resolution, reducing false triggers common with simple PIR sensors. Works in all lighting conditions: radarbased detection does not rely on visible light, so performance is consistent in darkness, glare, or indoor lighting changes. Privacy preserving sensing: detects presence and motion without capturing images or audio. Easy integration: cableequipped module simplifies wiring and mounting into existing systems and prototypes. Reliable and stable performance: designed as a dependable component for continuous operation in embedded applications. Main features and attributes Model: HLKLD2410C Frequency: 24 GHz mmWave using FMCW technique Function: human presence status and motion detection module Detection range: up to 5 meters for typical human targets Sensitivity: sensitivity detection for small motions and micromovements Connectivity: supplied with cable for straightforward electrical connection Form factor: compact sensor module suitable for embedded and retrofit installations Why customers need this module or supplement camera and PIR solutions when you need consistent presence detection in low light or visually sensitive areas. Improve energy efficiency by enabling precise occupancy control for lighting and HVAC systems. Add presence awareness to automation and security systems without adding video surveillance. Practical applications and use scenarios Smart lighting and HVAC control: use the module to detect occupancy in offices, conference rooms, hallways, or restrooms to trigger lighting and climate control only when spaces are occupied. Security and intrusion detection: integrate into alarm systems or perimeter sensors to detect human motion with reduced susceptibility to false alarms caused by pets or changing light. Industrial and IoT automation: deploy in factories, warehouses, or smart devices to monitor worker presence, trigger equipment start stop logic, or log occupancy data for operational workflows. Integration notes Designed as a sensor module for incorporation into controllers, microcontroller boards, or custom PCBs. Mount in locations with clear line of sight to the monitored area for detection performance. Use standard signal processing and systemlevel logic to interpret presence status and integrate into control systems. This HLKLD2410C module provides a compact, reliable way to add sensitive presence and motion detection to a wide range of products and systems while maintaining stable performance.
