Rd-03E is a radar module equipped with the S3KM111L chip and the S3KM111L chip of Silicon Microelectronics. S3KM111L is an integrated single-chip millimeter wave sensor SoC based on FMCW radar transceiver technology. It operates in the K band of 24 GHz, with a modulation bandwidth of up to 1 GHz for each single frequency scan. This module adopts FMCW waveform and advanced signal processing technology exclusive to S3 series chips, combined with MCU exclusive radar signal processing and built-in intelligent presence sensing algorithm, to achieve accurate human body sensing distance measurement and gesture recognition. Developers can display real-time distance information and gesture information through upper computer tools.
The Rd-03E module can detect and recognize moving and micro moving human bodies, and report real-time distance. It can detect targets and gestures in designated areas and report results in real time. It is widely used in various AloT scenarios. This module has the characteristics of strong real-time performance, high ranging accuracy, large ranging range, and flexible algorithm parameter configuration.
