Genuine Rd-01 24G Radar Human Body Detection Module, Radar + WiFi + BLE Module, Sensor Module

The Rd-01 module supports Wi-Fi and BLE. The radar section utilizes Silicon Motion's S3KM111L chip. The S3KM111L is an integrated monolithic single-wavelength sensor SoC based on FMCW radar technology. It operates in the 24GHz k-band, with a modulation bandwidth of up to 1GHz per frequency. It uses FMCW frequency-modulated continuous wave to detect targets within a designated space. Combined with radar signal processing and precise human body sensing algorithms, it achieves highly sensitive human presence detection, recognizing both moving and stationary human bodies. The Wi-Fi and BLE section uses the BL602 chip as the core processor, supporting Wi-Fi 802.11b/g/n protocols and BLE 5.0 protocol. The BL602 chip integrates a low-power 32-bit RISC CPU, 276KB RAM, and rich peripheral interfaces, including SPI, UART, I2C, PWMADC, and GPIO.
