Plug and play, easy assembly. Sensing distance up to 6 meters. Large detection angle, coverage up to ±60 degrees. Accurate identification within the range; supports sensing range division and interference shielding outside the defined zone. Multi-level intelligent parameter adjustment via Bluetooth or serial port for adapting to changing environments. Includes visual debugging and configuration tools. Compact design, minimum size only 16 × 22 mm. Supports ceiling-mount and wall-mount installation. Operates in the 24 GHz ISM band, compliant with FCC and CE spectrum regulations. Wide input voltage range: 5–12 V. The LD2410C human presence sensing module uses 24 GHz millimeter-wave radar sensor technology. Key advantages over alternative solutions include: 1. Detects not only moving humans but also static, micro-moving, seated, and reclining individuals—unlike traditional PIR-based sensors. 2. High environmental robustness: performance remains stable across variations in temperature, ambient light, humidity, and lighting conditions. 3. Strong material penetration capability: can be embedded inside enclosures without requiring apertures, preserving product aesthetics. 4. Adjustable maximum sensing distance and sensitivity per distance segment for precise, flexible configuration. The LD2410C module detects and classifies human presence during motion, micro-movement, standing, sitting, and lying postures. It supports multi-level parameter tuning and is suitable for AIoT applications such as: 1. Human presence-activated lighting control 2. Human presence-triggered wake-up for digital signage and similar devices
