HLK-LD2410D 24 GHz Human Presence Sensor, 5V Human Micromovement Detection Radar Module

The LD2410D is a stationary human presence sensor comprised of minimalist 24 GHz sensor hardware and intelligent micro-movement detection algorithm firmware. This hardware device includes a millimeter-wave AIoT sensor, a high-performance 24 GHz transceiver antenna, and peripheral circuitry. It utilizes millimeter-wave radar distance measurement technology and the radar chip's proprietary advanced radar signal processing to accurately detect movement, micro-movements, and human presence. The intelligent human presence detection algorithm firmware is primarily used indoors to detect movement, micro-movements, or the presence of a person in the area and update detection results in real time. Supported frequency band: 24 GHz - 24.25 GHz; Scan bandwidth: 0.25 GHz; Maximum equivalent isotropic radiated power: 11 dBm; LDO supply voltage: 5 V. Dimensions: 7 x 35 mm; Ambient temperature: -40°C to +85°C; Average operating current: 50 mA; Data refresh cycle: 165 ms; Detection range: static > Range: ≥ 4 m / dynamic ≥ 5 m

Distance resolution: 0.75 m

Detection angle: ±60°
