Sampling rate #14

Closed DominiqueMakowski closed 6 years ago

DominiqueMakowski commented 6 years ago

Hey, I do have a question and didn't find the answer in the data sheet.

What is the default / maximum sampling rate with which we can acquire ECG with this?

Thanks

You essentially find the bandwidth of the ECG signal and multiply by 10. So you have 40Hz bandwidth. And with 400Hz set as sampling rate. You should be good to go

@Fieryfire I am not sure, do you mean that 400Hz is a good sampling rate to acquire ECG data or that the maximum (or default) sampling rate that one can acquire with the AD8232 heart rate monitor is 400 Hz?

The AD8232 is only a signal conditioner. The output from it is analog. It is upto you to use a micro controller with an ADC to be able to sample the analog data For ex. using an arduino can get the job done
