IWR6843AOPEVM: Can I use IWR6843AOPEVM alone for breathe detection and human tracking?

Part Number: IWR6843AOPEVM
Other Parts Discussed in Thread: MMWAVEICBOOST, IWRL6432

Tool/software:

I'm working on a radar-based emergency detection system that involves both human tracking and respiration monitoring.

I want to know if it's possible to implement both of these features using only the IWR6843AOPEVM board, without DCA1000 or mmWaveICBoost.

A few specific questions:

  • Can I get access to enough data (e.g., point cloud, raw phase info, etc.) from the AOPEVM board alone to estimate respiration?

  • Are there any example labs or SDKs in the mmWave Industrial Toolbox that support these features with just the AOPEVM?

  • Is raw data access (for custom signal processing) possible over UART or another interface, without DCA1000?

    Hi

    Sorry for the delayed response.

    1. You can use only IWR6843AOPEVM for implementing and running the code for human tracking and respiration monitoring. But you will need mmWaveICBoost for debugging with CCS. So, I recommend using mmWaveICBoost along with IWR6843AOPEVM 

    2. You can refer to the vital signs demo using IWR6843AOPEVM at the below location

    radar_toolbox_3_00_00_05\source\ti\examples\Industrial_and_Personal_Electronics\Vital_Signs\Vital_Signs_With_People_Tracking

    But do note that source code is not shared with this demo. There is another demo with IWRL6432 where source code is available. You can refer to it at the below location

    3. You can send out the collected ADC data over UART but real time streaming is not possible. You can store some frames data and send it over UART. Also, you can store 1D fft data and send only the required data over UART for post processing instead of using the entire raw ADC data. If you need real time raw ADC data streaming, then you will have to use DCA1000
