The Rd-01 is a radar module created by Shenzhen Anxinke Technology Co., LTD, supporting Wi-Fi and BLE. It features the S3KM111L chip from Sidian Micro, which is a single-wave sensor SoC utilizing FMCW radar technology. Operating in the 24GHz band, it offers up to 1 GHz of modulation bandwidth. The FMCW continuous wave detects targets within a designated space. This, combined with signal processing and a precise human body sensing algorithm, allows for the detection of both motion and stillness in humans.
For Wi-Fi and BLE, the module uses the BL602 chip as its core processor, supporting Wi-Fi 802.11b/g/n and BLE 5.0. The BL602 includes a low-power 32-bit RISC CPU, 276KB RAM, and multiple peripheral interfaces such as SPI, UART, I2C, PWM, ADC, and GPIO. The Rd-01 can detect and report the presence of moving or stationary humans in real-time via Wi-Fi and BLE. It comes with visual configuration tools for easy setup of detection range, sensitivity, and delay times when no humans are detected. Additionally, it allows for the wireless configuration of radar parameters over Wi-Fi and BLE, enhancing the efficiency of installation, operation, and maintenance.
