HK-LD2410D 24G Human Presence Detection Module Millimeter-Wave Ra DAR Perception Switch Smart Sensor 0.75M Distance Measurement (Single Module)

HK-LD2410D 24G Human Presence Detection Module Millimeter-Wave Ra dar Perception Switch Smart Sensor 0.75M Distance Measurement Product Description The LD2410D is a stationary human presence sensor that combines minimalist 24 GHz sensor hardware with intelligent firmware for detecting human movement and presence. The hardware features an A loT millimetre-wave sensor, a high-performance 24 GHz transmit-receive antenna, and peripheral circuits. It utilises millimetre-wave ra dar distance measurement technology and advanced proprietary ra dar signal processing technology from the ra dar chip to achieve precise detection of movement, subtle motion, and human presence. The human presence detection intelligent algorithm firmware is primarily used in indoor scenarios to detect whether there is movement, micro-motion, or human presence within a designated area, and to continuously update detection results in real-time.
