The MRS251 series is an ultra-low-power, ultra-compact, and highly integrated millimeter-wave motion sensing AoB module, which incorporates a 24GHz millimeter-wave antenna, RF front-end, baseband processor, application processor, and 128KB NOR Flash in a single package.

Based on the Doppler principle of human movement detection, the MRS251 utilizes high-performance radar algorithms to achieve precise sensing of both body motion and subtle movements (micro-motion). With power consumption and dimensions comparable to PIR (Passive Infrared) sensors, it serves as an ideal replacement and upgrade for existing PIR-based human detection solutions.

The MRS251 integrates a complete SoC system, sensing algorithms, and application firmware. By enabling parameter configuration without development tools, it allows for rapid product deployment and one-click firmware generation.
