From the shop's description

Ai-Thinker Rd-04 10GHz Wave Radar Sensor The Ai-Thinker Rd-04 10GHz Wave Radar Sensor is an advanced motion perception module engineered for precise human presence detection across a variety of applications. Developed by Shenzhen Ai-Thinker Technology Co., Ltd., this module leverages the Phosense XBR818 chip, operating at a center frequency of 10.525GHz within the X-band radar spectrum (10.275–10.775GHz). Its design incorporates a 1T1R (1 Transmit, 1 Receive) antenna configuration, enabling directional transmission and reception for enhanced detection accuracy. Features: DIP package, standard 2.0mm pin header. The radar supports the 10.525G frequency band. Integrated digital signal detection and processor, real-time output of moving target detection results. Support IIC bus configuration. Support pulse power supply mode. Support integrated photosensitive drive. Support a variety of installation methods such as top hanging and wall hanging. The longest radar induction range is up to 6.5 meters. The radar detection Angle is large, and the coverage range can reach ± 50 degrees.
