Ai-Thinker Rd-04 is a 10GHz human motion sensing module based on X-band radar technology. The official Ai-Thinker documentation describes this Ai-Thinker radar sensor as a compact module built around the XBR818 chip with a center frequency of 10.525GHz, using a fixed-frequency 1T1R directional antenna design for stable and accurate motion detection.

Rd-04 is intended for smart lighting, smart switches, video doorbells, smart locks, pet feeders, and other low-power products that need reliable human motion sensing. Official materials also emphasize configurable delay, adjustable sensing range, optional photosensitive support, low-power pulse mode, and strong anti-interference performance, making this Ai-Thinker motion sensor module a practical choice for compact embedded sensing designs.

Features

  • 10.525GHz X-band radar for human motion sensing.
  • Directional 1T1R antenna design with stable signal processing.
  • Adjustable sensing range and delay setting support.
  • Low-power pulse mode down to microampere-level consumption according to official materials.
  • Strong anti-interference performance with clutter and harmonic suppression.
  • Suitable for Ai-Thinker smart lighting, motion sensing switches, and low-power embedded security products.
