The Rd-03 is a radar module equipped with the S3KM1110 chip, an integrated single-chip milli-metre wave sensor SoC based on the FMCW radar transceiver technology, which operates in the K-band at 24 GHz, with a modulation bandwidth of up to 1 GHz for each single-frequency scan to detect targets in the set space using FMCW continuous waves. Combined with radar signal processing to achieve high-sensitivity motion detection and micro-motion detection.
The Rd-03 module senses the presence of a moving or slightly moving human body in the area and achieves real-time detection results.
Provide visual configuration tools, can easily configure the sensing distance range, different zones of sensing sensitivity and unmanned delay time.
