Ai-Thinker Rd-04 10G Radar Module Human Micromotion, Motion Sensing Low Power Module Rd-04 Onboard Antenna – User-Freindly And Convenient

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 the 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 at 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., and can be widely used in all kinds of lamps, such as bulb lamps, downlights, ceiling lights, etc.; low power applications, such as visual doorbells, cat eyes, door lock, low power camera, intelligent litter box, pet feeder, etc.

Pin Description

Attention to testing and using radar module

In the installation position on the motherboard, the following ways are recommended:

• Try to ensure that the radar antenna is facing the area to be detected and that the antenna is open without shielding.
• To ensure that the radar installation position is firm and stable, the shaking of the radar itself will affect the detection.
• In the case of walls or obstacles reflecting microwave, the perceived distance and perceived Angle will have gained.
• In the case of open around, the perception distance and Angle will be attenuation; the microwave antenna can change detection, so please protect the antenna, and the surface without metal objects (such as solder wire), to avoid affecting the perception distance.
• The radar module maintains an independent use space, and the surrounding space maintains a free space interval of more than 2mm.
• About 15s initialized noise analysis time after power-on, during which it is abnormal perception work
• During production line testing and ageing operation, if a large number of radar modules are stacked to a block, there may be self-excitation phenomenon may occur. Please ensure that a safe distance of more than 50cm is maintained between the powered radar modules.

In order to meet the performance of the onboard antenna, it is forbidden to place metal parts around the antenna, away from high-frequency devices.
