IWR1642BOOST: People Counting Demo Enquiry

Part Number: IWR1642BOOST
Other Parts Discussed in Thread: IWR1642, , IWR6843, IWR6843AOP, MMWAVEICBOOST

Hi Team,

I have a customer who is looking into using IWR1642 for their people counting application (might expand more in the future). I have already watched the training videos and ran through the resources we have for IWR1642, however I still have a couple of question:

1.  There is a couple of packages in the IWR1642BOOST page, which package is most suited for the people counting demo?

2. My customer uses Nvidia Jetson (Nano & Xavier) and Raspberry Pi , will the IWR1642 be able to support their communication protocol?

3. Is the mmWave sensor able to detect metals? (e.g. Stolen metallic item, dangerous object detection and etc...)

Thank you very much!

  • Hello,

    Is there a specific reason the IWR1642 is desired? For a people counting application the IWR6843 is typically advised. Most people counting applications are required by regulations to use 60Ghz, not the 77GHz band used by the 1642. The most up to date people counting demo uses the IWR6843 or IWR6843AOP device with the below SW.

    1. I suggest the getting started with running application demos bundle. This will let you test the prebuilt applications. If you want to modify and debug the source code, I suggest the develop your application bundle that includes the MMWAVEICBOOST board.

    2. The data output is over UART at 921600 baud. Both SoC boards listed should be able to receive this.

    3. The IWR6843 will detect metal objects, but differentiating them from a person carrying them may be difficult. This level of sensitivity is not currently supported in the people counting demo. Is the idea to use this in place of a more traditional pass through metal detector?

  • Hi Jackson,

    Their company melt rebar to form different kinds of end products. There are a few cases where their employees are smuggling out the rebars daily to sell. I believe they are also planning to leverage on our mmWave technology to detect rebars rather than a traditional pass through metal detector. Is there any advise for such module?

    I believe it should be similar concept to the picture below, rather than gun, they are looking to detect rebars.

    Thanks Jackson for your help!

  • Hello Ernest,

    The metal will be detected, but it will likely be similar detection strength to the human body as well. You may be able to see a difference in signal strength but it will be difficult. You will need to test to see if a different signature can be detected with your objects, as it also depends on the size and shape of the objects.
