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.
