Human Micro-Motion Detection MmWave Sensor, 24GHz MmWave Radar, Based On S3KM1110, Adopts Frequency Modulated Continuous Wave (FMCW) Technology, Compact Size And Easy Integration

Features At A Glance

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
  • Supports UART port and GPIO header output, for connecting to host boards such as Raspberry Pi and Arduino
  • Wide-range moving human body sensing distance, supports top-mounted and wall-mounted detection
  • Comes with online resources and manual (examples for Raspberry Pi/RP2040/Arduino/ESP32/Jetson Nano)
