The LD2410D is a stationary human presence sensor consisting of minimalist 24 GHz sensor hardware and intelligent human micro-motion sensing algorithm firmware. The hardware features an AIoT millimeter-wave sensor, a high-performance 24 GHz transmit-receive antenna, and peripheral circuitry. It utilizes millimeter-wave radar distance measurement technology and the radar chip's advanced proprietary radar signal processing to accurately sense motion, micro-motion, and human presence.The human presence sensing intelligent algorithm firmware is mainly used in indoor scenarios to sense whether there is movement, micro-movement or the presence of a human body in the area, and refresh the detection results in real time., Manufacturer: Osmond
