Product description
HMMD-mmWave Sensor (Human Micro-Motion Detection). The HMMD-mmWave sensor is a radar-based sensor for detecting human micro-movements. It uses FMCW (Frequency Modulated Continuous Wave) technology. The sensor identifies moving, stationary, and motionless individuals. By combining radar signal processing with precise algorithms for human detection and distance measurement, it allows for individual adjustment of sensitivity in different zones, improving immunity to interference.
With low power consumption and simple integration, the sensor is suitable for a wide range of AIoT (Artificial Intelligence of Things) applications, such as smart homes, intelligent security systems, smart retail, and smart lighting.
