A low-power micro/motion sensing module is designed based on an X-band radar chip, with a center frequency of 10.525GHz. The design adopts a fixed-frequency, directional transmitting and receiving antenna (1T1R), and integrates functions such as intermediate frequency demodulation, signal amplification, and digital processing. It has a delay setting capability, facilitating independent parameter adjustment, and boasts advantages including not penetrating walls, anti-interference, small size, good clutter and high-order harmonic suppression effects, as well as high stability and consistency.
It is suitable for embedded installation and is not affected by temperature, humidity, oil fumes, water mist, etc. It can be widely applied to various types of lamps, such as bulb lights, downlights, ceiling lights, etc., and low-power application scenarios, such as video doorbells, peepholes, door locks, low-power cameras, etc.
