IWR6843ISK: Need helps for Outdoor people detection

Pranav Venu

Part Number: IWR6843ISK

Hi,

My application is to detect people within 50 m range with 40 degree or more azimuth angle. And I found this http://dev.ti.com/tirex/explore/node?node=AJymZUkImsF4knF6x3AKNg__VLyFKFf__LATEST by using IWR6843ISK. But I need to clarify the following things,

1) This lab ( http://dev.ti.com/tirex/explore/node?node=AJymZUkImsF4knF6x3AKNg__VLyFKFf__LATEST ) is designed for indoor conditions. But my requirement is for outdoors, is the same setup works fine for outdoors?

2) Is there any way to increase the range of detection to 70 meters?

3) If the system detected people then I need to blow an alarm, how can I do that? Is there any GPIO pins in the IWR6843ISK board to drive a relay for alarm?

Hi Pranav,

I've asked an expert to look into this and we should have an answer for you sometime next week.

Cheers,

Hi Pranav,

You linked this, which you can use the lab indoors and outdoors, we have tested mostly outdoors with the default configuration.
You can do this by changing the chirp slope (lower it). However, you may find this does not work, in which case please use the sensing estimator to generate a 70 meter chirp configuration.
GPIO pins are available on the EVM - please see the GPIO driver documentation in the SDK.

Regards,

Justin
