XENSIV™ 60-GHz Radar on Esp32

Overview

This code example demonstrates Infineon's radar presence solution to detect human presence within a configurable distance. Powered by the XENSIV™ 60-GHz radar, this solution provides extremely high accuracy in detecting both micro and macro motions. The ability to detect micro motion offers unique benefits over conventional technologies deployed to detect human presence, thus making it perfect for user interaction with devices.

This code example is ported from official ModusToolbox™ code example on Github/Infineon. For Operation instructions, please refer to the original README.md for more details.

Setup Environment

  • conda create --name env
  • conda activate esp
  • mkdir esp cd esp
  • ESP-IDF Toolchain Setup
  • git clone https://github.com/espressif/esp-idf.git
  • cd esp-idf
  • ./install.sh all
  • . ./export.sh
  • cd examples
  • Copy this radar folder inside example folder
  • idf.py build
  • Flash the files
  • idf.py flash
  • Monitor the output
  • idf.py monitor
  • To modify the WiFi, go to menuconfig and change the configuration
  • idf.py menuconfig
  • To change the radar settings, go to ./main/radar settings folder, find the target settings, copy and paste the target setting in the ./main/radar_settings_tr13.h

Running server to collect radar data over UDP

  • Go to scripts folder and run the udp server
  • python run_tcp_server.py --port=3333
  • Go to main folder and run idf.py monitor to monitor Esp32
  • Your radar data will be saved as csv file inside the scripts folder

Versioning

This code example adopts the following versioning convention: a.b.c+esp32-#, where

  • a.b.c refers to the upstream official version it's ported from
  • esp32 refers to the MCU platform
  • # refers to the build ID

How-to

This is a complete code example with sdkconfig for esp32 MCU platform.
