# HLK-LD2410C (Component) ## Description 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 ## Component Details - **Owner:** silicon-yard - **Created:** 7/26/2026 - **Last Updated:** 7/27/2026 - **Visibility:** Public - **Manufacturer Name:** Hi-Link - **Part Type:** Module - **Datasheet URL:** https://storage.googleapis.com/graviton-electric-symbols/document_assets/user-uploaded/a52edd67d960cb649bfcfd837845386dd73048298561124b2ab47bac281cf47b.pdf - **Manufacturer Part Number:** HLK-LD2410C - **Part Type:** Modules - **MPN:** HLK-LD2410C - **Mount Type:** Surface Mount - **Package / Case Code:** Module - **Pin Count:** 5 ## Pins | Pin | Name | Type | |-----|------|------| | 1 | UART_TX | | | 2 | UART_RX | | | 3 | OUT | | | 4 | GND | | | 5 | VCC | | --- *Generated from [https://www.flux.ai/silicon-yard/hlk-ld2410c](https://www.flux.ai/silicon-yard/hlk-ld2410c)*
