[Introduction]：E54-24LD12B is an outstanding life presence sensing sensor reference design that combines the efficient 24GHz mmWave sensor hardware E54-24LD12B with the intelligent algorithm firmware HPS01. The sensor hardware consists of an AIoT mmWave sensor chip, a high-performance one-transmit-one-receive microstrip antenna, an MCU, and supporting peripheral auxiliary circuits. The intelligent algorithm firmware HPS01 uses FMCW waveforms and chip-specific advanced signal processing technology. This solution is mainly aimed at conventional indoor environments such as homes, offices, and hotels to achieve accurate presence sensing of the human body.
