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

It 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 upto 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 accurate human body sensing algorithm, high sensitivity human presence state sensing can be realized to recognize human body in motion and 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 and unmanned delay time, etc.
