AJMRTC HLK-LD102 10GHz Hand Sweep Radar Sensor Module, Near-Field Wave Trigger Microwave Motion Detector, Dual UART Serial and IO Level Output, Comes with Pin Test Kit for Smart Cabinet Light, Non-con

AJMRTC HLK-LD102 is a 10G microwave radar sensing module designed for non-contact hand sweep trigger and short-range proximity induction. It adopts Doppler radar principle and can identify hand sweeping motion without physical touch. It supports two output methods: digital UART serial port for reading detection status and configuring parameters, and 3.3V GPIO level output for simple switch trigger directly connected to MCU IO pin. The sensing distance can be adjusted to fit hand sweep (10cm20cm) or near-body proximity detection (1m2m). Unlike infrared sensors, this radar can work normally behind plastic, wood and other non-metallic panels, so you can hide it inside cabinet panels, mirror lights and equipment shells without reserved sensing windows. The module features low power consumption, stable anti-interference performance and built-in adjustable hold delay and lock time. This package includes a supporting pin test kit to help makers finish wiring test and function verification faster. It is widely used for smart cabinet lights, wardrobe lights, mirror lamps, advertising screen trigger, non-contact switches and embedded IoT control projects. Metal barriers will block radar signals and cause detection failure; avoid installing near large metal surfaces.
