SmartElex Ai-Thinker RD-01 Radar Module equipped with AI-Thinker RD-01 Radar Wi-fi Bluetooth Module. This module supports Wi-Fi & BLE. Radar part is equipped with the S3KM111L chip of Sidian Micro. S3KM111L is an integrated monolithic single-wave sensor SoC based on FMCW radar technology.

Operates in 24GHzkband 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 accurate human body sensing algorithm, high sensitivity human presence state sensing can be realized to recognize human body in motion and static state.
