📡Rd-03E Radar Module with S3KM111L Chip
The Rd-03E is a radar module equipped with the S3KM111L chip that operates in the K-band at 24GHz with a modulation bandwidth of up to 1GHz per single frequency scan. It uses FMCW waveforms and advanced proprietary signal processing technology, combined with the MCU’s radar algorithms and built-in intelligent presence sensing, to achieve accurate human distance measurement and gesture recognition. Developers can display real-time distance and gesture information through the host computer tool. The Rd-03E module can detect, identify, and report the real-time distance of moving and micro-moving human bodies, detect targets and gestures in designated areas, and report results instantly. It is widely used in AloT scenarios. Key features include strong real-time performance, high measurement accuracy, wide detection range, and flexible algorithm parameter configuration.
