Ai-Thinker Rd-03 Radar Module – RS5725

Rd-03 is a radar module developed by Ai-Thinker. It is equipped with silicon micro-S3KM1110 chips. S3KM1110 is an integrated single-chip millimeter-wave sensor SoC based on FMCW radar transceiver technology. Operates in 24 GHz K-band with up to 1 GHz modulation bandwidth per frequency. FMCW continuous wave is used to detect the target in the set space. Combined with radar signal processing and an accurate human body sensing algorithm, high-sensitivity human presence state sensing can be realized to recognize a body in motion and a static state.

The Rd-03 module can sense whether there is a moving or micro-moving human body in the area, and realize real-time detection results. A visual configuration tool is provided to easily configure the sensing distance range, sensing sensitivity in different intervals unmanned delay time, etc.
