[Introduction]:E54-24LD12A is a wide coverage human micro-motion millimeter wave sensor, which includes a minimalist 24GHz sensor hardware and human micro-motion sensing intelligent algorithm firmware. The hardware is equipped with AIoT millimeter wave sensors, high-performance 24GHz one-transmit-one-receive antennas and peripheral circuits; the human micro-motion sensing algorithm uses millimeter wave radar distance measurement technology and advanced proprietary radar signal processing technology to achieve accurate perception of moving, micro-moving and standing human bodies. Plug and play, it can be flexibly applied to different smart scenarios and terminal products.
