Battery-powered mmWave radar sensor with sub-1-GHz and Bluetooth® 5.2 reference design

TIDA-010254

Design files

Overview

This industrial reference design demonstrates the use of a battery powered IWRL6432 60-GHz mmWave radar with a sub-1 GHz or Bluetooth® 5.2 wireless communication. This design has been demonstrated with people-counting and tracking, and motion tracking applications from a Li-battery that send out the result to a remote host by sub-1G or Bluetooth, while also compatible with any existing IWRL6432 software. This reference design uses a LAUNCHXLCC1352R1 wireless microcontroller LaunchPad™ with a PC GUI to visually show radar sensing data and detecting results.

Features
  • Low-power mmWave radar leveraging 57-GHz to 64-GHz capable IWRL6432
  • Long-range, low-power sub-1 GHz or BLE wireless connectivity using the CC1352R
  • Battery powered for high-efficiency and small form factor
  • Power optimized test results
  • Demonstrates people counting and tracking software
