2PCS Human Micro-Motion Detection mmWave Sensor, Compatible with Raspberry Pi/Pi Pico/Jetson Nano/ESP32, 24GHz mmWave Radar, Frequency Modulated Continuous Wave (FMCW) Technology, UART & GPIO Output

Overview 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. It can be widely used in AIoT scenarios such as Smart Home, Intelligent Security, Smart Business, and Intelligent Lights, etc. 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 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, Compatible with Raspberry Pi / Pi Pico / Jetson Nano / ESP32/ Ar-dui-no.

Wide-range moving human body sensing distance, supports top-mounted and wall-mounted detection Comes with online resources and manual: bit. ly/4e0yvzb
