AI-Thinker RD-03E Radar Module

Rd-03E is a radar module developed by Shenzhen Ai-Thinker Technology Co., LTD. 

It equipped with silicon micro-S3KM111L chip. S3KM111L is an integrated single-chip millimeter-wave sensor SoC based on FMCW radar transceiver technology. Operates in24GHz k band with up to 1 GHz modulation bandwidth per frequency. The module adopts FMCW waveform and advanced signal processing technology proprietary to S3 series chips. Combined with MCU's proprietary radar signal processing and built-in intelligent presence sensing algorithm, it can realize accurate human body sensing distance measurement and gesture recognition. Developers can display distance information and gesture information in real time through the host computer tool. The Rd-03E module can detect and identify moving and micro-moving human bodies, and report real-time distances.

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 configuration of algorithm parameters.
