IWRL1432BOOST: DETECTION RANGE FOR IWRL1432(LEVEL SENSING)

Amara Rakesh
Intellectual 321 points
Part Number: IWRL1432BOOST
Other Parts Discussed in Thread: IWRL1432

Tool/software:

I am currently using the IWRL1432 board for a level sensing application. After flashing the pre-built binary, I am using the default configurations. However, the maximum detection range is only 3 meters, whereas I need at least 10 meters.

To achieve this, I used the mmWave Sensing Estimator to generate configurations, but I couldn’t find specific settings for level sensing.

  1. Could you provide configuration settings for a 10-meter detection range or point me to a relevant source?
  2. In the command channelCfg 1 1 0, I understand that it enables 1 TX and 1 RX. To increase the detection range, should I enable additional TX and RX channels?
  3. If I enable all 3 RX and 2 TX, what will be the expected power consumption?

Thanks & Regards,
Amara Rakesh

    Hi,

    I suppose the default configuration present in the radar toolbox provides a maximum detection range of 10 meters. Could you check if you are selecting the right default configuration? 

    Multiple TX and RX support is not available for level sensing demo. It uses only 1 TX and 1 RX.

    Regards,

    Hi,

    1.I am using the correct configurations, located at the following path:

    C:\ti\radar_toolbox_2_30_00_12\source\ti\examples\Industrial_and_Personal_Electronics\Level_Sensing\high_accuracy_low_power_sensors\chirp_configs

    This configuration defines the maximum and minimum range, correct?
    For example, in rangeSelCfg 0.0 10.0, the max range is set to 10m, even though the sensor typically supports 3–4 meters.

    2.I also have a small curiosity: The IWRL1432 board comes with 3 RX and 2 TX antennas. Since the level-sensing application uses only 1 RX and 1 TX, what is the purpose of the remaining antennas?

    Thanks && Regards

    Hi,

    What do you exactly refer by even though the sensor typically supports 3–4 meters?

    The level sensing demo can definitely support 10 meters with the default configuration.

    We have different demos for various use cases(example: motion and presence detection) where we use multiple TX and RX. 

    Regards

    Hello, 

         "even though the sensor typically supports 3–4 meters", not this "Even though I used the same configuration, I observed a maximum detection range of 3–4 meters in the GUI application. I will verify this again.

    What is the maximum detectable range for level sensing?

    Thanks for your guidance.

    Hi,

    We could detect objects clearly at a distance of around 30 meters.
