24 GHz Human Presence Radar Sensor Module – 24 GHz FMCW millimeter-wave human presence detection module designed for smart home automation, occupancy sensing, lighting control, security systems, industrial automation, IoT devices, and embedded presence detection applications. Operates from a 5 V to 12 V supply with a typical current consumption of 79 mA and detects both moving and stationary human targets using Frequency-Modulated Continuous Wave (FMCW) radar technology. Features a UART digital communication interface, configurable detection thresholds, event/occupancy detection, high immunity to ambient light, temperature, smoke, and dust, and supports motion, micro-motion, and static presence detection without requiring direct line-of-sight. The module measures 22 × 16 mm, is designed for surface-mount installation, and operates over a −40°C to +85°C temperature range, making it suitable for long-term embedded and industrial deployments. #HiLink #HLKLD2410CP #HLKLD2410C #24GHzRadar #HumanPresenceSensor #FMCWRadar #OccupancySensor #MotionDetection #UART #IoT #SmartHome #EmbeddedSystems
