Child-presence and occupant-detection reference design using 60-GHz antenna-on-package mmWave sensor


Design files


This reference design demonstrates the use of the AWR6843AOP, a 60-GHz single-chip mmWave sensor with integrated antenna. The sensor also has an integrated DSP, MCU, and a hardware accelerator for fast Fourier transform (FFT) processing.

The AWR6843AOP sensor can help developers address a wide range of in-cabin sensing applications, including use cases like detection of a child across two rows of a car, seatbelt warning, and intruder detection. The small form factor enables placement of the sensor in locations like overhead console around the rearview mirror, in the headliner, B/C pillars, and seats. It provides flexibility to Tier 1s and carmakers in planning end-use cases.

  • Demonstration hardware and software using AWR6843AOP for multifunctional sensing
    • Child-presence detection
    • Seat-occupancy detection
    • Intruder detection
  • Approximate azimuth field of view (FoV) of 120° and elevation FoV of 120°
  • Signal processing for point-cloud detection handled onboard AWR6843AOP using integrated HWA, DSP, and R4F
  • Integrated antenna on package (AoP) and small form factor enables flexible mounting positions, including overhead roof mount
