Ai Thinker Rd-04

Rd-04 is a motion sensing module based on X-band radar developed by Ai-Thinker The module uses Phosense’s XBR818 chip, and center frequency is 10.525GHz. The module design adopts fixed frequency, directional transmitting and receiving antenna (1T1R), integrates the functions of medium frequency demodulation, signal amplification and digital processing, and has the ability of delay setting and adjustable perception range. The module has the advantages of no wall penetration, anti-interference, small size, good suppression effect of clutter and high harmonic, high stability and consistency. In the module pulse power supply mode, the power consumption is in the micro-ampere level. The module is mainly aimed at low-cost and low-power consumption applications. The module is suitable for embedded concealed installation, not affected by temperature / humidity, lampblack, water mist, etc., can be widely used in all kinds of lamps, such as bulb lamp, downlight, ceiling light, etc.; low power application, such as visual doorbell, cat eye, door lock, low power camera, intelligent litter box, pet feeder, etc.
