I recently purchased the MR60BHA1 60GHz board for testing, but it seems there’s quite a bit of error in heart rate measurement. Therefore, I’m planning to retest using the GUI tool from the demo in 2022 video that had a significant influence during purchase. Where can I find it?
During the measurement, I connected to a PC via UART communication and maintained a distance of 50-100cm while sitting on a chair. The sensor height was placed at the level of the chest. Are there any additional settings available to reduce the error further?
Also, it seems to calculate breath rate and heart rate every 3 seconds, but even when holding my breath, the breath rate doesn’t immediately drop to zero but decreases slowly. I’m curious about how it’s calculated.
