24GHz Millimeter Wave Radar Micro Motion Sensor S3KM1110 Chip

Introduction HMMD mmWave Sensor is a human micro-motion sensor that can detect and recognize moving, standing, and stationary human body. It is widely used in various AIoT scenarios, covering smart homes, smart security, smart businesses, and smart lighting, etc. Features Comes with the Silicon Micro AIoT Millimeter-Wave Sensor SoC S3KM1110. Onboard high-performance 24GHz one-transmit-one-receive antenna and peripheral circuits. Mini module size: 20mm x 20mm. Pre-loaded with default human body sensing configuration, plug-and-play. Longest detection distance compatible with motion human body sensing: 8.5m. Driven by the PY32F003F17U6TR microcontroller, with UART pins exposed compatible with easy integration with Arduino/ESP32/JetsonNano and other main control boards. Utilizes human micro-motion sensing algorithms, millimeter-wave radar distance measurement technology, and advanced proprietary signal processing technology of the S3KM1110 chip. Provide online comprehensive supporting documentation (Raspberry/JetsonNano/Arduino/ESP32/sample demos). Accurate perception of motion, micro-movement, and stationary human bodies achieved.
