Ai-Thinker Rd-03E Radar Sensor Module

Description:

The Rd-03 is a radar module created by Ai-Thinker, featuring the S3KM1110 chip from Iclegend. The S3KM1110 is a SoC that integrates a microcontroller and a mmWave sensor, utilizing FMCW radar transceiver technology. Operating in the K-band at 24GHz, the Rd-03E offers a modulation bandwidth of up to 1GHz for each single-frequency sweep. It employs FMCW frequency modulation continuous wave for target detection within a predefined space. This technology, combined with advanced radar signal processing, enables the detection of high-sensitivity motion and micro-motion.

This module is capable of detecting the presence of moving or micro-moving human bodies within a specified area, providing real-time detection results. It comes with a visual configuration tool that simplifies the setup of sensing distance range, sensitivity at various intervals, and the delay time for unmanned periods.
