IWR1443BOOST: Level sensing and lense

HS FAE Germany

Part Number: IWR1443BOOST

Hello,
in the following video we mentioned to use a lense for level sensing:
https://training.ti.com/fluid-level-sensing-demonstration-using-ti-mmwave-sensors?cu=1135109

- What lense was used?
- Can the lense be used with the booster pack?
- Is a lense always needed for level sensing? When is a lense needed?

Regards, Holger

    Hi Holger,

    Unfortunately we do not have any information about the lens that was used but it is possible to use for any of the mmWave Devices.

    The need of a lens depends on an application and this is same for level sensing. Since the lens concentrates the beam to a much smaller area it will make sense for many level sensing applications, although may not if the medium being measured was solid or uneven. In that instance a broader field of view would be desirable.

    Akash,
    in the video you explained that you used a lense. Why can't you tell more about that lense?

    Regards, Holger

    Hi Holger,

    The Lens in that demo was borrowed from a systems engineer and no one is sure of the origin. We also do not have access to it anymore unfortunately.

    While I cannot recommend a specific lens manufacturer on E2E forums, I would make sure the lens you are looking at appropriate for mmWave with a design frequency of >100GHz. If you would like to discuss further feel free to email me.

    Regards,
