The HLK-LD2410 5V 24GHz Human Presence Radar Sensor Module is an advanced millimeter-wave radar sensor capable of detecting both moving and stationary human presence with exceptional accuracy. Operating at 24GHz frequency, this compact sensor utilizes FMCW radar technology to provide reliable motion and occupancy sensing in various environments.
Unlike traditional PIR sensors, the LD2410 can detect subtle human movements such as breathing, making it highly suitable for smart lighting systems, security monitoring, automatic doors, occupancy detection, and intelligent automation applications. The module supports serial communication and can easily interface with Arduino, ESP32, Raspberry Pi, STM32, and other microcontroller platforms.
