DESIGN GUIDE

People counting and tracking using mmWave radar sensor with sub-1 GHz reference design

Description

This design demonstrates the use of the IWR6843 device, a single-chip, mmWave radar sensor from TI with integrated DSP, for an indoor and outdoor people-counting application along with sub-1 GHz wireless communication. This reference design uses the MMWAVEICBOOST and IWR6843ISK evaluation modules (EVMs) together with the LAUNCHXL-CC1352R1 wireless MCU LaunchPad™. This solution is shown to localize people out to 6 m (short-range configuration) and 14 m (long-range configuration).

Features

  • Contains demonstration hardware and software to use the IWR6843 device and mmWave radar sensor for people counting and tracking
  • Long-range, low power sub-1 GHz wireless connectivity using the CC1352 device
  • IEEE 802.15.4e or IEEE 802.15.4g stack with collector and sensor application
  • mmWave technology provides the range, velocity, and angle information – ideal for environmental effects
  • Azimuth field of view of 120° across a distance of 6 m, that can extend to 14 m with different chip configuration
  • Examples of implementation of static clutter and group- tracking algorithms

Applications

  • Occupancy detection
  • Motion detector
  • Automated doors and gates
  • IP network camera
  • Smoke and heat detector
  • Lighting sensors
