LD2410C — 24 GHz FMCW human presence detection module Key benefits Detects real human presence reliably: uses FMCW (frequency-modulated continuous wave) radar plus dedicated signal processing and detection algorithms to identify people in a defined indoor space. Captures both motion and micro-movements: senses moving targets and very small or stationary human movements (for example breathing or slight body shifts) that typical PIR sensors miss. Provides distance and auxiliary information: reports target distance and other supporting data to enable localization and smarter system behavior. Easy to tailor and integrate: real-time output with a configuration tool to set detection range, sensitivity by interval, and unattended delay time for your application needs. What it does (function and performance) Sensing method: FMCW FM continuous wave radar optimized for human detection. Detection range: up to 6 meters. Range resolution: 0.75 meter. Detection capability: identifies moving people and stationary persons exhibiting micro-movements. Outputs: real-time presence detection and distance/auxiliary information for downstream processing. Important attributes Model: LD2410C. Intended environment: indoor use. Sensitivity and behavior can be adjusted via the provided configuration tool (detection distance range, interval sensitivity, unattended delay time). Built-in radar signal processing and a refined human-detection algorithm for improved sensitivity and reduced false positives. Practical use scenarios Smart building automation: switch lighting, HVAC, or ventilation based on detected occupancy and distance to avoid unnecessary energy use while recognizing stationary occupants. Security and access control: supplement door/window sensors or cameras by reliably detecting human presence, including low-motion or motionless intruders in a room. Assisted-living and space monitoring: non-contact presence monitoring to confirm if a person is present in a room or bed, including detection of micro-movements, while preserving privacy. Why choose LD2410C Focused on accurate indoor human-presence detection where micro-movements matter. Tunable performance to match sensitivity, range, and delay requirements for different applications. Delivers both presence and distance information to support decision-making in automation, security, and monitoring systems. Note: LD2410C is a highly sensitive 24 GHz module for detecting human presence and is intended for indoor deployment with configuration options provided as described.
