AJMRTC HLK-LD2450 24G millimeter wave radar set includes 5 trajectory tracking modules. It locates moving human targets in real time and transmits coordinate and velocity data via serial communication. Built-in algorithms remove the requirement for complicated radar signal processing development. It performs reliably for wall-mounted indoor sensing such as smart light triggering, security entry detection, hotel occupancy judgment and robot trajectory sensing. Radar signals are unaffected by clothing, smoke or low light, making it a robust non-contact induction solution for small-batch IoT prototyping and testing projects.
