The RD-04 is an X-band radar-based motion sensor module developed by Ai-Thinker using Phosense's XBR818 chip and a center frequency of 10.525GHz. Modular design using fixed frequency, directional transmitting and receiving antenna (1T1R), integrated mid-frequency demodulation, signal amplification and digital processing functions, and at the same time has the ability to set the delay and adjust the perception range.
This module has the advantages of anti-interference, small size, high stability and consistency. This module is mainly aimed at low power consumption and low cost applications. The module is suitable for hidden installation, unaffected by temperature, humidity, light bulb, water mist, etc.,
The module can be widely used in lamps, such as light bulbs, spotlights, ceiling lights, etc.; low energy applications, such as visual doorbells, door locks, low power cameras, smart litter boxes, pet feeders, etc.
