IWR6843: Minimum distance of sensor

Part Number: IWR6843
Other Parts Discussed in Thread: AWR1642, AWR1843

Right now I'm looking for mmWave sensors that have the minimum sense distance. I notice that the minimum distance of IWR6843 is about 3-3.75cm.

Is there any other sensor that has a shorter sensing distance？ It would be great that you can recommend me some.

Looking forward to your reply.

Hi Jingxiao,

You are correct this is the minimum distance. Some other sensors might be able to overcome this such as Ultrasonic and Time of Flight Sensors.

Cheers,

Hi Akash

Thanks for your advice!

By the way, I do a little search of Ultra short-range radar, and the result is AWR1843 – Single-chip 76-GHz to 81-GHz automotive radar sensor integrating DSP, MCU and radar accelerator and AWR1642 – Single-chip 76-GHz to 81-GHz automotive radar sensor integrating DSP and MCU. I can't find the minimum sense range of those two. May you help me with it?

Looking forward to your reply.
