Description
The HMMD-mmWave sensor is a sensor for human micro-movements that utilizes Frequency Modulated Continuous Wave (FMCW) technology to detect and identify moving, stationary, and resting human bodies. By combining radar signal processing with precise algorithms for human detection and distance measurement, it supports independent sensitivity configuration for each area to improve interference resistance. Due to its compact size, low power consumption, and easy integration, it is ideal for AIoT scenarios such as smart home, intelligent security, smart business, and smart lighting.
