Human Micro-Motion Detection mmWave Sensor, 24GHz mmWave Radar, Based On S3KM1110, Adopts FMCW Technology
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.
The HMMD-mmWave-Sensor is a human micro-motion sensor, adopts Frequency Modulated Continuous Wave (FMCW) technology to detect and identify moving, standing, and motionless human body. Combining radar signal processing with accurate human detection and ranging algorithms, supports configuring the sensibility for each range independently to improve anti-interference performance. Compact size, low power consumption, and easy integration, it can be widely used in AIoT scenarios such as Smart Home, Intelligent Security, Smart Business, and Intelligent Lights, etc.
