Waveshare 26536 - Human Micro-Motion Detection MmWave Sensor S3KM1110 24GHz, FMCW Technology - HMMD-mmWave-Sensor
The Human Micro-Motion Detection mmWave Sensor (S3KM1110) delivers reliable human presence detection using FMCW radar at 24 GHz. It combines on-board MCU and human micro-motion algorithms for accurate ranging and detection of moving, micro-motion, and stationary humans. Designed with UART and GPIO outputs, it’s ready for integration into AIoT projects, especially on Raspberry Pi, Arduino, ESP32, Pico, or Jetson Nano platforms.
Features
- 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 detection of movements, 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)
