How is the Breathing Rate Calculated in the MR60BHA2?

Tom60 · April 2, 2026, 9:10am

Hello everyone,

I previously posted a question on the forum about the inconsistency between the breathing rate and the breathing phase output. The link is below:
https://forum.seeedstudio.com/t/mr60bha2-breath-rate-consistently-shows-4-bpm-offset/295177

I would like to ask how the breathing rate output of the MR60BHA2 radar is calculated.

Is it calculated directly from the breathing phase using FFT, or does it rely on other reference signals as well?

Thank you.

Hi there,

SO , Boi you are not the ONLY one… LOL
Unfortunately it’s still not open source and still a guarded secret.
Something new is coming… word on the street better and open.
