LD2410C — 24 GHz FMCW human-presence radar module Key benefits Reliable detection of people in indoor spaces, even when subjects are standing still or making only micro-movements. Real-time output for immediate integration into monitoring, control, or alerting systems. Compact, sensor-class solution for occupancy sensing, elder-care monitoring, security, and energy management where non-contact detection is required. What it does and how it works Uses 24 GHz FMCW (frequency-modulated continuous wave) radar to detect human targets within a defined space. Applies a precise person-detection algorithm in radar signal processing to identify human presence, track motion, and calculate target distance. Outputs detection results in real time for downstream systems to act on. Performance and important specifications Detection frequency: 24 GHz. Detection method: FMCW radar with person-detection signal processing. Maximum detection range: up to 5 meters. Distance resolution: 0.75 meter. Detects moving and stationary human bodies and micro-movements. Designed primarily for indoor use. Integration and compatibility Provides processed detection results suitable for integration into existing monitoring or control systems. Designed to work with radar signal-processing pipelines; consult the LD2410C datasheet and technical documentation for detailed interfacing and electrical specifications. Practical attributes Indoor-rated sensor module intended for presence/movement detection applications. Outputs are generated in real time to support immediate decision-making or automation. See official product documentation for mechanical dimensions, mounting recommendations, electrical interface details, and material specifications. Typical applications and use scenarios Smart lighting and HVAC control: Automatically adjust lighting or climate systems based on confirmed human presence to save energy and improve comfort. Elder-care and fall-monitoring assistance: Detect micro-movements or the absence of expected motion to provide timely alerts while preserving privacy (non-camera). Indoor security and access monitoring: Provide reliable presence detection for small indoor areas such as entryways, corridors, storage rooms, or server closets. What makes LD2410C stand out High sensitivity to both motion and micro-movement, enabling detection of stationary people as well as those in motion. Combined hardware and person-detection algorithm provide distance information and reliable real-time outputs up to 5 meters. Operates at 24 GHz using FMCW technique, a common radar approach for accurate ranging in compact modules.
