Which is the best sensor for breath-rate in sleep?

Hey Seeed-team

you have different sensors that can detect breathing:

Which of those is better to measure real-time respiratory data on a human lying in bed under a blanket?

Thanks

HI, for mmWave sensors, the higher the frequency, the higher the resolution and the better the penetration, so it is recommended that you choose a 60GHZ radar

this is contradictory to everything I know about how waves behave. Are you 100% sure about that?

Hello, the effect of 60GHZ is better than 24GHZ, this is the result of the test.

Thanks.

Is it fast enough that, once a respiratory rate readout is established, to immediately show changes?
F.e. if I sit in front of it and hold my breath, will it be able to detect this within which time?

Thanks again.

Hello, in the latest version of the 60GHz Breathing Heartbeat Radar, we have added a new feature of sleep, which is also designed for sleep monitoring. With this radar, you can see important messages such as sleep quality score, number of rollovers, number of times you leave the bed, deep sleep, light sleep, time awake, etc. New Wiki content will also be updated in the near future.

The rapid detection you mention is actually not quite in principle in our case. What the radar is measuring is the average respiratory and heart rate results, which would require a certain amount of time for the measurement.
