HLK-LD102 near-field microwave radar sensor adopts Doppler radar principle for non-contact hand sweep induction. It can detect waving hand motion to turn lights or switches on/off, widely used for cabinet lamps, under-counter lighting and touchless control projects. It provides both GPIO level output and UART serial communication, so you can read status data or adjust parameters via serial commands. The sensing distance and hold time are customizable to fit different usage requirements. The included pin test kit helps you finish bench testing without extra soldering. It runs on wide voltage and features low power consumption, perfect for smart home DIY, induction light, automatic switch and touchless interactive equipment.
