LD2410C — 24 GHz human presence radar sensor Key benefits Reliable detection of human presence in indoor spaces, including both obvious motion and very small micro-movements (e.g., breathing or subtle shifts). Reduces false negatives by combining FMCW continuous-wave radar with radar signal processing and a dedicated human-detection algorithm. Real-time output and configurable parameters let you tune detection behavior for different environments and use cases. How it solves problems Detects occupants when conventional PIR sensors fail (for example, when people are nearly stationary). Provides distance and auxiliary information to support smarter control logic (lighting, HVAC, access, or monitoring systems). Configurable sensitivity and unattended delay reduce nuisance triggers while ensuring occupancy is captured when needed. What makes it stand out Uses FMCW FM continuous-wave radar plus proven signal processing and a human-body detection algorithm for high sensitivity and reliable presence recognition. Detects both moving and stationary targets and estimates target range and other auxiliary information. Designed for indoor use with real-time output and a supplied configuration tool for fast setup and tuning. Key features and performance Model: LD2410C. Operating band: 24 GHz radar. Detection range: up to 6 meters. Range resolution: 0.75 m. Detection capability: moving targets and stationary targets with micro-movements. Outputs detection results in real time. Includes a configuration tool to adjust: Detection distance range, Detection sensitivity across selectable intervals, Unattended delay time and related parameters. Integration and compatibility Provides real-time detection outputs suitable for integration into building automation, safety, and monitoring systems. Configuration tool enables rapid parameter tuning to match local installation conditions and system requirements. (Interfaces and mechanical details should be confirmed from the technical datasheet or integration guide for system-specific wiring and mounting.) Practical applications Smart lighting control: reliably turn lights on or off based on real presence detection, including people who are nearly stationary. HVAC and energy management: adjust ventilation and heating/cooling according to real occupancy rather than motion-only triggers. Security and assisted living monitoring: detect presence and micro-movements for unattended-occupancy alerts or to confirm well-being without cameras. Usage notes Intended primarily for indoor deployments; performance is specified up to 6 meters with 0.75 m resolution. Use the provided configuration tool to optimize detection distance, sensitivity, and delay for each installation environment. Consult the product technical documentation for mounting recommendations, electrical interfaces, and system integration details. LD2410C is a high-sensitivity 24-GHz solution for accurate, real-time human presence detection in indoor applications.
