Description
Specifications

This Human Micro-Motion Detection MmWave Sensor with a 24GHz MmWave Radar, is based on S3KM1110 and adopts Frequency Modulated Continuous Wave (FMCW) Technology with Compact Size And Easy Integration.

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.

Based on AIoT mmWave Sensor SoC S3KM1110, onboard high performance 24GHz 1T1R antennas
Onboard MCU and built-in human micro-motion sensing algorithm for accurate detecting of moving, micro-motion, and standing human
Provides UART communication protocol, supports configuring sensing distance range, sensitivity, and absence report delay, easy to operate
