AJMRTC HLK-LD2410D 24GHz Millimeter Wave Human Presence Radar Sensor Module, FMCW Perception Switch, 0.75m Distance Resolution, Supports GPIO & UART Output, Smart Human Detection Module Only

AJMRTC HLK-LD2410D human presence radar module adopts FMCW 24GHz millimeter wave technology. It can detect not only walking motion but also static human presence and tiny body tremors that PIR sensors fail to capture. It divides the sensing area by 0.75m resolution gates; you can configure detection distance, zone sensitivity and unmanned hold delay via supporting debugging software. It provides GPIO level trigger for simple switch control and UART serial port to upload detailed radar data. It works reliably in complete darkness and can penetrate thin glass, wood and plastic panels. This sale is for the radar module itself only, excluding brackets, power adapters and wiring harnesses. It is widely used for smart light switches, cabinet lighting, bathroom sensors, home automation, Arduino / ESP32 / Raspberry Pi IoT projects and automatic door trigger systems.
